3e7ddf02dc Make dpaa work with only slightly modified Linux device trees.
Linux has a slightly different device tree definition for DPAA than originally
done in the FreeBSD driver.  This changes the driver to be mostly compatible
with the Linux device tree definitions.  Currently the differences are:

bman-portals: compatible = "fsl,bman-portals" (Linux is "simple-bus")
qman-portals: compatible = "fsl,qman-portals" (Linux is "simple-bus")
fman: compatible = "fsl,fman" (Linux is "simple-bus")

The Linux device tree doesn't specify anything for rgmii in the mdio.  This
change still requires the device tree to specify the phy-handle, and doesn't yet
support tbi.

4f8155ddbc Add support for LOADER_RC setting in the pkgfs manifest (defaults to
/loader.rc) to specify a Forth file to read from the pkgfs tarball and
process by Ficl.

This allows for the tarball to do runtime things like load a
platform-specific FDT blob, among other things.

cbd6713146 Loader paged/pageable data is not always paged.
This change does modify devsw dv_print() to return the int value,
enabling walkers to interrupt the walk on non zero value from dv_print().

This will allow the pager_print actually to stop displaying data on
user input, and additionally pager is used in various *dev_print callbacks,
where it was missing.

For test, lsdev [-v] command should display data by screenfuls and should
stop when the key 'q' is pressed on pager prompt.

97371ba2a9 zfsbootcfg: a simple tool to set next boot (one time) options for zfsboot
(gpt)zfsboot will read one-time boot directives from a special ZFS pool
area.  The area was previously described as "Boot Block Header", but
currently it is know as Pad2, marked as reserved and is zeroed out on
pool creation.  The new code interprets data in this area, if any, using
the same format as boot.config.  The area is immediately wiped out.
Failure to parse the directives results in a reboot right after the
cleanup.  Otherwise the boot sequence proceeds as usual.

zfsbootcfg writes zfsboot arguments specified on its command line to the
Pad2 area of a disk identified by vfs.zfs.boot.primary_pool and
vfs.zfs.boot.primary_vdev kenv variables that are set by loader during
boot.  Please see the manual page for more.

Thanks to all who reviewed, contributed and made suggestions!  There are
many potential improvements to the feature, please see the review for
details.

75a63b2de3 Really make WITHOUT_FORTH (MK_FORTH==no) work. The recent inclusion of
FICL definitions not in ficl/ficl32 files broke this generally. This
makes that stuff conditional on BOOT_FORTH. Also, move definitions
related to the architecture (FICL_CPUARCH and friends) into
Makefile.ficl that all parts of the tree that include files with ficl
need to include (but only if MK_FORTH == yes). In addition, had to fix
library ordering issue with LIBSTAND to keep it last. Without boot
forth, there's no references to memset to bring in memset.o from
libstand.a to satisfy libgeliboot.a's use of it. Listing libstand last
solves this issue (and it's the proper place for libstand to boot).

dc9b124d66 Create a new MACHINE_ARCH for Freescale PowerPC e500v2
Summary:
The Freescale e500v2 PowerPC core does not use a standard FPU.
Instead, it uses a Signal Processing Engine (SPE)--a DSP-style vector processor
unit, which doubles as a FPU.  The PowerPC SPE ABI is incompatible with the
stock powerpc ABI, so a new MACHINE_ARCH was created to deal with this.
Additionaly, the SPE opcodes overlap with Altivec, so these are mutually
exclusive.  Taking advantage of this fact, a new file, powerpc/booke/spe.c, was
created with the same function set as in powerpc/powerpc/altivec.c, so it
becomes effectively a drop-in replacement.  setjmp/longjmp were modified to save
the upper 32-bits of the now-64-bit GPRs (upper 32-bits are only accessible by
the SPE).

Note: This does _not_ support the SPE in the e500v1, as the e500v1 SPE does not
support double-precision floating point.

Also, without a new MACHINE_ARCH it would be impossible to provide binary
packages which utilize the SPE.

Additionally, no work has been done to support ports, work is needed for this.
This also means no newer gcc can yet be used.  However, gcc's powerpc support
has been refactored which would make adding a powerpcspe-freebsd target very
easy.

Test Plan:
This was lightly tested on a RouterBoard RB800 and an AmigaOne A1222
(P1022-based) board, compiled against the new ABI.  Base system utilities
(/bin/sh, /bin/ls, etc) still function appropriately, the system is able to boot
multiuser.

d3bf5efc1f Fix device delete child function.
When detaching device trees parent devices must be detached prior to
detaching its children. This is because parent devices can have
pointers to the child devices in their softcs which are not
invalidated by device_delete_child(). This can cause use after free
issues and panic().

Device drivers implementing trees, must ensure its detach function
detaches or deletes all its children before returning.

While at it remove now redundant device_detach() calls before
device_delete_child() and device_delete_children(), mostly in
the USB controller drivers.

afd9d8d0cb In UEFI mode expose the SMBIOS anchor base address via kenv so the kernel
etc. can find out where the SMBIOS entry point is located.  In pure
UEFI mode the BIOS is not mapped into the standard address space so the
SMBIOS table might not appear between 0xf0000 and 0xfffff.  The
UEFI environment can report this the location of the anchor.  If it is
reported then expose it as hint.smbios.0.mem.  This can then be used
by other tools.  However, we should make smbios(4) useful and have it
take this value and provide accesor function so ipmi(4) etc. don't
have to parse and figure things about the SMBIOS table.  I have some
simple patches to smbios(4) to expose this address as sysctl and
for ipmi(4) to get the base address.  However, the real fix is to
have ipmi(4) ask smbios(4) for what it wants and have smbios(4)
parse it out and return it.  This would make smbios(4) useful and reduce
duplicated code.  If this address doesn't point to the anchor then
finding SMBIOS info. will fail as if this didn't exist.  So there should
be no harm.

With this change and the following hack, dmidecode works on a bunch of
UEFI machines that I tested:

  if kenv hint.smbios.0.mem > /dev/null
  then
        mkdir -p /sys/firmware/efi
        mount -t tmpfs -o size=8k tmpfs /sys/firmware/efi
        echo "SMBIOS=`kenv hint.smbios.0.mem`" > /sys/firmware/efi/systab
  fi

Linux exposes this information via the /sys/firmware/efi/systab file which
dmidecode looks at.  We should update dmidecode to do this the FreeBSD
way when we determine what that is!

Since command_errmsg is pointer to actual error message, which can be static

5c6b397ff1 The getsecs() function is implemented in platform- and bootfw-specific
files and, in a number of these places, there were problems with how they
were declared.

Some used int return instead of time_t. On some architectures the bit
width of time_t did not naturally fit into an integer and could lead to
some unexpected behavior. (For example, 32-bit ARM builds uses a 64-bit
time_t.)

Make sure the function prototypes always specify void for the argument
list when they do not have any arguemnts, otherwise some compilers can
complain about the prototype.

67330db0bb Simple post-mortem reporter for amd64 loader.efi.
There is no way to see anything about the faults occuring in
loader.efi. Some intel BIOSes do output a line into serial port at
115200/8/1 regardless of the current port settings with the EFI error
number, but this is too little, and not always available, esp. if the
user does not know where to look.

The patch adds a simple facility to grab exceptions and at least dump
generic registers and some exception details.  Due to the relative
complexity of correctly taking over the BIOS IDT setup, only install
the facility on user request.

Two new commands, 'grab_faults' and 'ungrab_faults' are provided,
first one takes over, second undoes the first. It is supposed that
user would execute 'grab' by the developer direction of collecting the
debugging data.  The 'fault' command generates exception to test the
setup.

Fault handlers use dedicated stack to improve chances of catching
stack/TSS exceptions.  Due to this, BIOS IDT is duplicated into a
private copy, and debugger needs to find a free GDT slot for TSS. This
is done in somewhat complicated efi_redirect_exceptions().

6a695123b0 Netboot: allow both tftpfs and nfs in both pxeboot and loader.efi
Add a new 'netproto' variable which can be set for now to
NET_TFTP or NET_NFS (default to NET_NONE)

From the dhcp options if one sets the root-path option to:
"ip:path", the loader will consider it is booting over NFS
(meaning same behaviour as the default current behaviour)

if the dhcp option "tftp server address" is set (option 150)
the loader will consider it is booting over tftpfs, it will then
consider the root-path options with 2 possible case
1. "path" then the IP of the tftp server will be the one passed by
the option 150, and the files will be retrieved under "path" on the tftp
server
2. "ip:path" then the IP of the tftp server will be the one passed in
the option "overwritting the IP from the option 150.

We could not "abuse" the rootpath option in the form or tftp://ip:path because
this is already used for other purpose by iPXE preventing any chainload from
iPXE to the FreeBSD loader.

Given at each open(), the loader loops over all available filesystems and keep
the "best" error, we needed to prevent tftpfs to fallback on nfs and vice versa.
the tftpfs and nfs implementation in libstand now return EINVAL early if
'netproto' for that purpose.

0b1c7ee322 Create a hook 'post-initialize' for people that want to define
something (perhaps in loader.rc.local) that can read in .conf files
after all the other .conf files have been read and override settings
in them. This is quite handy if the .conf file name is determined
while the loader is running, but might be generically useful for other
things. If this hook exists, call it, otherwise don't do anything.

Doing it in these functions ensures that this file is reliably
read. It also works around a defect in forth where s" isn't allowed
outside a function (well, in a compile context) leading to gross
workarounds if one were to hack loader.rc like:

: maybe-some-func s" some-func" sfind if execute else drop then ;
maybe-some-func

which somehow seems worse. Though I'm sure there's some clever forthy

99cbd70f0b The read-ahead code from r298230 made it likely the boot code would read
beyond the end of disk. r298900 added code to prevent this.  Some BIOSes
cause significant delays if asked to read past end-of-disk.

We never trusted the BIOS to accurately report the sectorsize of disks
before and this set of changes.  Unfortuately they interact badly with
the infamous >2TB wraparound bugs.  We have a number of relatively-recent
machines in the FreeBSD.org cluster where the BIOS reports 3TB disks as 1TB.

With pre-r298900 they work just fine.  After r298900 they stop working if
the boot environment attempts to access anything outside the first 1TB on
the disk.  'ZFS: I/O error, all block copies unavailable' etc.  It affects
both UFS and ZFS if they try to boot from large volumes.

This change replaces the blind trust of the BIOS end-of-disk reporting
with a read-ahead clip to prevent reads crossing the of end-of-disk
boundary.  Since 2^32 (2TB) size reporting truncation is not uncommon,
the clipping is done on 2TB aliases of the reported end-of-disk.
ie: a 3TB disk reported as 1TB has readahead clipped at 1TB, 3TB, 5TB, ...
as one of them is likely to be the real end-of-disk.

This should make the loader on these broken machines behave the same as
traditional pre-r298900 loader behavior, without disabling read-ahead.

As the support for large blocks was enabled in loader zfs code, the
heap in userboot was left not changed, resulting with failure of detecting
and accessing zfs pools for bhyve virtual machines.

This fix does set the heap to use same amount of memory as the zfsloader
is using. To make it possible to test and verify loader functions, bhyve
is providing very useful option, but it also means, we like to keep feature
parity with [zfs]loader as close as possible.

Using skein from freebsd crypto tree.
Since loader itself is using 64MB memory for heap, updated zfsboot to

Note, adding additional features does increate zfsboot code, therefore
this update does increase zfsboot code to 128k, also I have ported gptldr.S
update to zfsldr.S to support 64k+ code.

With this update, boot1.efi has almost reached the current limit of the size

4deb8929ea Make boot code and loader check for unsupported ZFS feature flags
OpenZFS uses feature flags instead of a zpool version number to track
features since the split from Oracle. In addition to avoiding confusion
on ZFS vs OpenZFS version numbers, this also allows features to be added
to different operating systems that use OpenZFS in different order.

The previous zfs boot code (gptzfsboot) and loader (zfsloader) blindly
tries to read the pool, and if failed provided only a vague error message.

With this change, both the boot code and loader check the MOS features
list in the ZFS label and compare it against the list of features that
the loader supports. If any unsupported feature is active, the pool is
not considered as a candidate for booting, and a helpful diagnostic
message is printed to the screen. Features that are merely enabled via
zpool upgrade, but not in use, do not block booting from the pool.

a1acc06f4f Random bit generator (RBG) driver for RPi and RPi2.
Summary:
This driver supports the following methods to trigger gathering random bits from the hardware:
1. interrupt when the FIFO is full (default) fed into the harvest queue
2. callout (when BCM2835_RNG_USE_CALLOUT is defined) every second if hz is less than 100, otherwise hz / 100, feeding the random bits into the harvest queue

If the kernel is booted with verbose enabled, the contents of the registers will be dumped after the RBG is started during the attach routine.

Author: hackagadget_gmail.com (Stephen J. Kiernan)

Test Plan: Built RPI2 kernel and booted on board. Tested the different methods to feed the harvest queue (callout, interrupt) and the interrupt driven approach seems best. However, keeping the other method for people to be able to experiment with.

dc87c22a61 fix a zfs boot regression introduced in r300117 by accident
There is no reason to return non-zero value from zfs_probe_partition()
as that causes following partitions to not be probed for ZFS vdevs.
A particular scenario that I encountered is a GPT partitioned disk
where several partitions have freebsd-zfs type.  A partition with a lower
index is used as a cache (l2arc) vdev and in that case case zfs_probe()
returned a non-zero status.  That status was returned to ptable_iterate()
and caused it to abort the iteration.  Because of that the subsequent
partitions were not probed and a root pool was not discovered resulting
in a boot failure.

While there fix the style for nearby return statements.

TDMA and CESA registers are placed in different ranges of memory. Split
memory resource in DTS to reflect that. This change is needed to support
multiple CESA nodes as otherwise the ranges of different nodes would
overlap.

In consequence, CESA_WRITE and CESA_READ macros have been split depending
on which range of registers is accessed. Offsets for CESA registers have
been modified as the base address has changed.

4e865d9eb0 Fix unit number of EFI net interfaces and ignore psuedo network interfaces.
In r277943, the efinet_match() routine was changed to use an off by one
when matching network interfaces.  The effect was that using "net1"
actually used the device attached to "net0".

Digging into the hardware that needed this workaround more, I found that
UEFI was creating two simple network protocol devices for each physical
NIC.  The first device was a "raw" Ethernet device and the second device
was a "IP" device that used the IP protocol on top of the underlying
"raw" device.  The PXE code in the firmware used the "IP" device to pull
across the loader.efi, so currdev was set to "net1" when booting from the
physical interface "net0".  (The loaded image's device handle referenced
the "IP" device that "net1" claimed.)

However, the IP device isn't suitable for doing raw packet I/O (and the
current code to open devices exclusively actually turns the "IP" devices
off on these systems).

To fix, change the efinet driver to only attach to "raw" devices.  This
is determined by fetching the DEVICE_PATH for each handle which supports
the simple network protocol and examining the last node in the path.  If
the last node in the path is a MAC address, the device is assumed to be
a "raw" device and is added as a 'netX' device.  If the last node is not
a MAC address, the device is ignored.

However, this causes a new problem as the device handle associated with
the loaded image no longer matches any of the handles enumerated by
efinet for systems that load the image via the "IP" device.  To handle
this case, expand the logic that resolves currdev from the loaded image
in main().  First, the existing logic of looking for a handle that
matches the loaded image's handle is tried.  If that fails, the device
path of the handle that loaded the loaded image is fetched via
efi_lookup_image_devpath().  This device path is then walked from the
end up to the beginning using efi_handle_lookup() to fetch the handle
associated with a path.  If the handle is found and is a known handle,
then that is used as currdev.  The effect for machines that load the
image via the "IP" device is that the first lookup fails (the handle
for the "IP" device isn't claimed by efinet), but walking up the
image's device path finds the handle of the raw MAC device which is used
as currdev.

With these fixes in place, the hack to subtract 1 from the unit can now
be removed, so that setting currdev to 'net0' actually uses 'net0'.

3e5a19be71 Add some routines for working with EFI DEVICE_PATH objects.
- efi_lookup_devpath() uses the DEVICE_PATH_PROTOCOL to obtain the
  DEVICE_PATH for a given EFI handle.
- efi_lookup_image_devpath() uses the LOADED_IMAGE_DEVICE_PATH_PROTOCOL
  to lookup the device path of the device used to load a loaded image.
- efi_devpath_name() uses the DEVICE_PATH_TO_TEXT_PROTOCOL to generate
  a string description of a device path.  The returned string is a CHAR16
  string that can be printed via the recently added '%S' format in
  libstand's printf().  Note that the returned string is returned in
  allocated storage that should be freed by calling
  efi_free_devpath_name().
- efi_devpath_last_node() walks a DEVICE_PATH returning a pointer to the
  final node in the path (not counting the terminating node).  That is,
  it returns a pointer to the last meaninful node in a DEVICE_PATH.
- efi_devpath_trim() generates a new DEVICE_PATH from an existing
  DEVICE_PATH.  The new DEVICE_PATH does not include the last
  non-terminating node in the original path.  If the original DEVICE_PATH
  only contains the terminating node, this function returns NULL.
  The caller is responsible for freeing the returned DEVICE_PATH via
  free().
- efi_devpath_handle() attempts to find a handle that corresponds to a
  given device path.  However, if nodes at the end of the device path do
  not have valid handles associated with them, this function will return
  a handle that matches a node earlier in the device path.  In particular,
  this function returns a handle for the node closest to the end of the
  device path which has a valid handle.

26f47fdd8f Add FDT overlays support to ubldr
FDT overlays is de-facto standard for describing expansion boards like
Beaglebone capes or Raspberry Pi shields. The ides is to have basic
DTB for base board and overlays DTB for shields/capes and to construct
final DTB either using human-readable configuration or some
self-discovery mechanism. I believe this approach can also be expanded
to support dynamically loadable FPGA bitstreams on systems like
Zedboard/Zybo.

Overlaying process is simmilar to executable link process for
binaries: each DTB has "exported" symbols and "undefined" symbols, the
latter are resolved using information for the former obtained from
base DTB or one of the overlays applied earlier (more rare case).

This symbols information is not generated by standard dtc that FreeBSD
has in base system, patched[1] version required to produces
overlay-compatible blobs. So although DTB files generated by
buildkernel do not support overlays there are enough
vendor/community-provided DTB blobs ciruclating around to justify
committing this change to ubldr.

This commit introduces handler for "fdt_overlays" variable that can be
defined either as a loader env variable or U-Boot env variable.
fdt_overlays is comma-separated list of .dtbo files located in
/boot/dtb/ directory along with base .dtb. ubldr loads files and
applies them one-by-one to base .dtb and then passes result blob to
the kernel.

rounddown2 tends to produce longer lines than the original code
and when the code has a high indentation level it was not really

This tries to strike a balance between readability using the macros
and flexibility of having the expressions, so not everything is

87ed2b7f5a A new implementation of the loader block cache
The block cache implementation in loader has proven to be almost useless, and in worst case even slowing down the disk reads due to insufficient cache size and extra memory copy.
Also the current cache implementation does not cache reads from CDs, or work with zfs built on top of multiple disks.
Instead of an LRU, this code uses a simple hash (O(1) read from cache), and instead of a single global cache, a separate cache per block device.
The cache also implements limited read-ahead to increase performance.
To simplify read ahead management, the read ahead will not wrap over bcache end, so in worst case, single block physical read will be performed to fill the last block in bcache.

Booting from a virtual CD over IPMI:
0ms latency, before: 27 second, after: 7 seconds
60ms latency, before: over 12 minutes, after: under 5 minutes.

89f8f24077 Import Mediatek/Ralink dtsi patches against OpenWRT dtsi files
This revision suggests dtsi patches to be used with the original OpenWRT
dtsi files so we can re-use what has already been done in OpenWRT for the
Mediatek/Ralink SoCs.

The only thing that is required after importing this revision should be
the following:
1. Import OpenWRT dts/dtsi files into sys/gnu/dts/mips
2. Run the following script in sys/gnu/dts/mips:
for f in `ls [mr]t*.dtsi`; do
printf "\n#include <fbsd-$f>\n" > $f
done

This will apply our dtsi patches to OpenWRT's dtsi files and will allow us
to re-use dts/dtsi files for ~170 Mediatek/Ralink boards.

Currently our drivers are not 100% compatible with OpenWRT's dts files, but
they're compatible enough.
We can add more functionality in the future that would better leverage the
OpenWRT work as well.

bd3bce41db Deprecate using hints.acpi.0.rsdp to communicate the RSDP to the
system. This uses the hints mechnanism. This mostly works today
because when there's no static hints (the default), this value can be
fetched from the hint. When there is a static hints file, the hint
passed from the boot loader to the kernel is ignored, but for the BIOS
case we're able to find it anyway. However, with UEFI, the fallback
doesn't work, so we get a panic instead.

Switch to acpi.rsdp and use TUNABLE_ULONG_FETCH instead. Continue to
generate the old values to allow for transitions. In addition, fall
back to the old method if the new method isn't present.

Add comments about all this.

- MPIC driver was added to files.armada38x, ARM_INTRNG option enabled in

Instead of modifying Armada38X DTS, offsets to CPU registers defined in

in ArmadaXP to state compliant with Linux DTS.

Additionally, required ARM_INTRNG definitions were added to mv_common.c.

08190ef7de Improve U-Boot API detection
Until now, ubldr has been trying to locate the U-Boot API using a hint
address (U-Boot's current stack pointer), aligning it to 1MiB and going
over a 3MiB (or 1MiB in case of MIPS) memory region searching for a
valid API signature.

This change introduces an alternative way of doing this, namely the
following:
- both U-Boot's bootelf and go commands actually pass argc and argv to
  the entry point (e.g., ubldr's start function, but they should also
  be passed over to main() transparently)
- so, instead of trying to go and look for a valid API signature, we
  look at the parameters passed to main()
- if there's an option '-a' with argument, which is a valid hexadecimal
  unsigned  long number (x), we try to verify whether we have a valid
  API signature at address x. If so - we use it. If not - we fallback
  to the original way of locating the API signature.

The U-Boot change, which causes the API structure address to be
exported as an environment variable, was committed to mainline U-Boot
as commit 22aa61f707574dd569296f521fcfc46a05f51c48

20893a44b7 Since kernel modules can now contain sections of type SHT_AMD64_UNWIND,
the boot loader should not skip over these anymore while loading images.
Otherwise the kernel can still panic when it doesn't find the .eh_frame
section belonging to the .rela.eh_frame section.

Unfortunately this will require installing boot loaders from sys/boot
before attempting to boot with a new kernel.

a1b701d82b This review aims at introducing ubldr (loader with U-Boot interface) for MIPS
(32 and 64-bit, LE and BE).
The changes were tested with QEMU's 'mips' target.

Most of the implementation was lifted from the ARM version, the appropriate
MIPS-specific things were implemented.

With these changes I am able to go all the way through the u-boot->ubldr->kernel
boot chain in QEMU on all combinations of bit-ness and endian-ness.

For the tests I've used FAT32 disk images (as FAT32 is supported by U-boot),
which include /boot/kernel/kernel and /boot/kernel/ubldr.bin

In U-boot I do:
fatload ide 0 <LOAD_ADDR> /boot/kernel/ubldr.bin; go <LOAD_ADDR>
where LOAD_ADDR is 80800000 for 32-bit and ffffffff80800000 for 64-bit

Then it's the usual ubldr that takes over and loads and starts a kernel.

b981b8bd86 These changes attempt to put things in order before the introduction of MIPS
ubldr.

The changes are mostly dealing with removing unnecessary casts from the U-Boot
API (we're passing only pointers, no obvious reason to cast them to uint32_t),
cleaning up some compiler warnings and using the proper printf format
specifiers in order to be able to compile cleanly for both 32-bit and 64-bit
MIPS targets.

0d2550a169 If the user has set a u-boot env var named rootpath, automatically
import it into the loader(8) env as dhcp.root-path, so that it overrides
any dhcp/bootp server-provided path.

Now if you have a dhcp server available you can easily net-boot a u-boot
system even if you don't control the dhcp server config, by setting just
two variables in the u-boot env:

  loaderdev=net
  rootpath=<nfsserverip>:<pathname>

Previously you had to either accept all the dhcp parameters from the
server without the ability to locally provide the rootpath, or you had
to forego dhcp and set more vars (ipaddr, netmask, serverip, rootpath).

4b68de9c1a Move the Allwinner kernels to use fdt_pinctrl. This will read the pin
configuration from the FDT data, then set the pins into the requested
state. As part of this the gpio controller now reports the correct number
of pins instead of returning the number of bank * 32.

To allow for a future consolidated kernel we add the SOC_ALLWINNER_A10 and
SOC_ALLWINNER_A20 kernel options. These need to be set as appropriate for
the SoC the kernel will boot on.

95b2d200ef Temporary overwrite bad definition of elm interrupt property in Linux
dts files. It may be removed once it will be fixed upstream.

This is done just to supresses a warning during dtb evaluation as
there is no elm driver in tree at present.

907fe11655 Update of the Allwinner drivers to:
* Use the Linux compat string
 * Use EARLY_DRIVER_MODULE to attach at the right time
 * Add a generic A10 kernel config file
 * A20 now use generic_timer
 * Add two new dts files for Olimex boards
 * Update our custom DTS file for A10 and A20 to use the same compatible
   property names as the vendor ones.

35ad131a2a Don't set the offset when loading the kernel on the arm loader.efi. The
copyin and copyout code handle virtual addresses such that they will take
a virtual address and convert it into a valid physical address. It may
also mean we fail to boot as the elf files load address could be 0.

214d450501 Stop clang from generating movt/movw sequences. These don't get relocated
so will access data from an unrelocated address. This is only needed for
self relocating code on ARMv7, however this is true for both ubldr and
loader.efi, the only two loaders we support on ARMv7.

While here also force the fpu to be none as is done in libstand.

aeffd7b7ea Ensure the bss is aligned to a 4-byte address as we use 4-byte aligned
stores to clear it.

While here reduce the alignment of the data from 4k to 16 byte aligned.
This should be more than enough, without wasting too much space.

595b2caa3f ficl: Replace rand(3) with random(3).
Be a little more consistent with random(3) and push an
unsigned value.

Again, this has no effect as this code doesn't get compiled
for the boot code.

9868276d3b ficl: Replace rand(3) with random(3).
While the later is a better random generator than the former, the main
reason of the change is that random() has a better chance to work with
libstand(3).

At this time we don't include random number generators in bootforth
so this has no effect.

1e97830083 Implement -P for boot loader. It's a bit easier to implement here than
in boot1, like is normally done. When a keyboard appears in the UEFI
device tree, assume -D -h, just like on a BIOS boot.

# It is unclear if an ACPI keyboard appearing in the tree means there's
# a real keyboard or not. A USB keyboard doesn't seem to appear unless
# it is really there.
