4c0a9db94a U-Boot API glue improvements:
- extend ub_dev_read() and ub_dev_recv() so that the actual len and
  all error codes can be passed and processed properly; unify behaviour of
  these routines

- introduce syscall general error code (API_ESYSC)

d221204d90 Backout rev 183181. It appears that I should have been using boot-device
of "cd:,\\:tbxi" with properly configured boot.tbxi, instead of booting
\boot\loader directly. Rev 183168 could probably stay, since it can be
viewed as an anti-foot-shooting measure and has no impact on normal
operation. I can revert it as well, if anybody objects.

d873f46379 On PowerPC send output to both "/chosen/stdout" and "screen" nodes, unless
they point to the very same device. This should make loader usable on
some (all?) PowerMacs, where "/chosen/stdout" is disconneted from the
"screen" by the OF init process by default, except when user actually
has requested interaction with OF by holding ALT-CMD-O-F. Along with
rev 183168 this should provide a way to build bootable FreeBSD/ppc
installation or live CD that works OOB. Also, it should bring PowerMac
experience closer to that on other arches.

4028a36726 Revert r177108 and restore r60506 for sparc64 as long as libstand
isn't fixed to only open the network device once and not do a open
and close dance on every file access; the firmwares of newer sparc64
machines perform an auto-negotiation with every open which in turn
causes netbooting to take horribly long if we open and close the

2611aba180 USIII and beyond CPUs have stricter requirements when it comes
to synchronization needed after stores to internal ASIs in order
to make side-effects visible. This mainly requires the MEMBAR #Sync
after such stores to be replaced with a FLUSH. We use KERNBASE as
the address to FLUSH as it is guaranteed to not trap. Actually,
the USII synchronization rules also already require a FLUSH in
pretty much all of the cases changed.
We're also hitting an additional USIII synchronization rule which
requires stores to AA_IMMU_SFSR to be immediately followed by a DONE,
FLUSH or RETRY. Doing so triggers a RED state exception though so
leave the MEMBAR #Sync. Linux apparently also has gotten away with
doing the same for quite some time now, apart from the fact that
it's not clear to me why we need to clear the valid bit from the
SFSR in the first place.

b2b88c5cb4 Use current SP instead of global data ptr for the U-Boot API signature search hint.
Global data (pointed by R2 on PowerPC) in principle is not guaranteed to be in
proximity of U-Boot heap (where the API signature is placed) accross different
architectures and platforms. Instead, use U-Boot stack pointer as a hint for
the search instead of the global data; this method tends to be more uniform
accross different platforms.

20e6aaf533 - Read ASI_{D,I}TLB_DATA_ACCESS_REG twice in order to work around
errata of USIII and beyond (USIII erratum #19, USIII+ erratum #1,
  USIIIi erratum #1).
- Use the cheetah PA mask in {d,i}tlb_va_to_pa_sun4u() for USIII
  and beyond. This is done so that these functions will still mask
  the debug bits of spitfire-class CPUs once we increase TD_PA_BITS
  to match the number of bits used for the PA by cheetah-class CPUs.
- Change {d,i}tlb_enter_sun4u() to also set TLB_CTX_KERNEL as the
  context of the mappings entered. This is more or less cosmetic as
  TLB_CTX_KERNEL is 0.
- Now that we have to distinguish between different sun4u CPUs in
  the loader anyway, no longer do trial and error when reading the

042df2e2da Enable GCC stack protection (aka Propolice) for userland:
- It is opt-out for now so as to give it maximum testing, but it may be
  turned opt-in for stable branches depending on the consensus.  You
  can turn it off with WITHOUT_SSP.
- WITHOUT_SSP was previously used to disable the build of GNU libssp.
  It is harmless to steal the knob as SSP symbols have been provided
  by libc for a long time, GNU libssp should not have been much used.
- SSP is disabled in a few corners such as system bootstrap programs
  (sys/boot), process bootstrap code (rtld, csu) and SSP symbols themselves.
- It should be safe to use -fstack-protector-all to build world, however
  libc will be automatically downgraded to -fstack-protector because it
  breaks rtld otherwise.
- This option is unavailable on ia64.

Enable GCC stack protection (aka Propolice) for kernel:
- It is opt-out for now so as to give it maximum testing.
- Do not compile your kernel with -fstack-protector-all, it won't work.

25eed6867e Implement a workaround for a long-standing problem in
libi386's time(), caused by a qemu bug.  The bug might
be present in other BIOSes, too.

qemu either does not simulate the AT RTC correctly or
has a broken BIOS 1A/02 implementation, and will return
an incorrect value if the RTC is read while it is being
updated.

The effect is worsened by the fact that qemu's INT 15/86
function ("wait" a.k.a. usleep) is non-implmeneted or
broken and returns immediately, causing beastie.4th to
spin in a tight loop calling the "read RTC" function
millions of times, triggering the problem quickly.

Therefore, we keep reading the BIOS value until we get
the same result twice.  This change fixes beastie.4th's
countdown under qemu.

894e70e80d Workaround a bug in the BIOS of Dell R900 machines. Specifically, each
entry in the SMAP is a 20 byte structure and they are queried from the
BIOS via sucessive BIOS calls.  Due to an apparent bug in the R900's
BIOS, for some SMAP requests the BIOS overflows the 20 byte buffer
trashing a few bytes of memory immediately after the SMAP structure.  As
a workaround, add 8 bytes of padding after the SMAP structure used in
the loader for SMAP queries.

7572ed5a08 Eliminate artificial increasing of 'netdev_opens' counter in loader's net_open().
This was introduced as a workaround long time ago for some Alpha firmware
(which is now gone), and actually prevented net_close() to ever be
called.

Certain firmwares (U-Boot) need local shutdown operations to be performed on a
network controller upon transaction end: such platform-specific hooks are
supposed to be called via netif_close() (from within net_close()).

This change effectively reverts the following CVS commit:

    sys/boot/common/dev_net.c

    revision 1.7
    date: 2000/05/13 15:40:46;  author: dfr;  state: Exp;  lines: +2 -1
    Only probe network settings on the first open of the network device.
    The alpha firmware takes a seriously long time to open the network device
    the first time.

Also suppress excessive output while netbooting via loader, unless debugging.

While there, make sys/boot/uboot more style(9) compliant.

4937cb2d30 Change the BTX kernel to drop all the way out to real mode to invoke BIOS
routines (V86 requests from the client and hardware interrupt handlers):
- Install trampoline real mode interrupt handlers at IDT vectors 0x20-0x2f
  to handle hardware interrupts by invoking the appropriate vector (0x8-0xf
  or 0x70-0x78).  This allows the 8259As to use vectors 0x20-0x2f in real
  mode as well as protected mode will ensuring that the master 8259A
  doesn't share IDT space with CPU exceptions in protected mode.
- Since we don't need to reserve space for page tables and a page directory
  anymore since dropping paging support, move the TSS and protected mode
  IDT up by 16k.  Grow the ring 1 link stack by 16k as a result.
- Repurpose the ring 1 link stack to be used as a real mode stack when
  invoking real mode routines either via a V86 request or a hardware
  interrupts.  This simplifies a few things as we avoid disturbing the
  original user stack.
- Add some more block comments to explain how the code interacts with the
  V86 structure as this wasn't immediately obvious from the prior comments
  (e.g. that we explicitly copy the seg regs for real mode out of the V86
  struct onto the stack to be popped off when going into real mode, etc.).
  Also, document some of the stack frames we create going to real mode and
  back.
- Remove all of the virtual 86 related code including having to simulate
  various instructions and BIOS calls on a trap from virtual 86 mode.
- Explicitly panic if a user client attempts to perform a V86 CALL
  request that isn't a far call.
- Bump version to 1.2.

Assuming this works ok this should fix some of the long standing issues
with USB booting as well as etherboot.

77c843cc10 Clean up PowerPC loader(8) build config.
Turn off TFTP support by default: when both TFTP and NFS are enabled in the
loader, strange interactions occur in the pure netbooting scenario (i.e.
loader is TFTP-ed, kernel+world mounted over NFS), leading to very slow access
to the NFS-exported files.

3e6468f751 Load the bytes into the EMAC's MAC address register in the proper
order.  The kernel used to shuffle them around to get things right,
but that was recently fixed.  This makes our boot loader match the
behavior of most other boot loaders for the atmel parts.  This bug was
inherited from the Kwikbyte loader that we started from.

This bug was discovered by Bj.ANvrn KNvnig back in June, but fell on the
floor.  He provided patches to the kernel, include backwards
compatibility options that were similar to Olivier's if_ate.c commit.

f352a0d45f First cut at support for booting a GPT labeled disk via the BIOS bootstrap
on i386 and amd64 machines.  The overall process is that /boot/pmbr lives
in the PMBR (similar to /boot/mbr for MBR disks) and is responsible for
locating and loading /boot/gptboot.  /boot/gptboot is similar to /boot/boot
except that it groks GPT rather than MBR + bsdlabel.  Unlike /boot/boot,
/boot/gptboot lives in its own dedicated GPT partition with a new
"FreeBSD boot" type.  This partition does not have a fixed size in that
/boot/pmbr will load the entire partition into the lower 640k.  However,
it is limited in that it can only be 545k.  That's still a lot better than
the current 7.5k limit for boot2 on MBR.  gptboot mostly acts just like
boot2 in that it reads /boot.config and loads up /boot/loader.  Some more
details:
- Include uuid_equal() and uuid_is_nil() in libstand.
- Add a new 'boot' command to gpt(8) which makes a GPT disk bootable using
  /boot/pmbr and /boot/gptboot.  Note that the disk must have some free
  space for the boot partition.
  - This required exposing the backend of the 'add' function as a
    gpt_add_part() function to the rest of gpt(8).  'boot' uses this to
    create a boot partition if needed.
- Don't cripple cgbase() in the UFS boot code for /boot/gptboot so that
  it can handle a filesystem > 1.5 TB.
- /boot/gptboot has a simple loader (gptldr) that doesn't do any I/O
  unlike boot1 since /boot/pmbr loads all of gptboot up front.  The
  C portion of gptboot (gptboot.c) has been repocopied from boot2.c.
  The primary changes are to parse the GPT to find a root filesystem
  and to use 64-bit disk addresses.  Currently gptboot assumes that the
  first UFS partition on the disk is the / filesystem, but this algorithm
  will likely be improved in the future.
- Teach the biosdisk driver in /boot/loader to understand GPT tables.
  GPT partitions are identified as 'disk0pX:' (e.g. disk0p2:) which is
  similar to the /dev names the kernel uses (e.g. /dev/ad0p2).
- Add a new "freebsd-boot" alias to g_part() for the new boot UUID.

2143962647 Rework the read/write support in the bios disk driver some to cut down
on duplicated code and support 64-bit LBAs for GPT.
- The code to manage an EDD or C/H/S I/O request are now in their own
  routines.  The EDD routine now handles a full 64-bit LBA instead of
  truncating LBAs to the lower 32-bits.  (MBRs and BSD labels only
  have 32-bit LBAs anyway, so the only LBAs ever passed down were 32-bit).
- All of the bounce buffer and retry logic duplicated in bd_read() and
  bd_write() are merged into a single bd_io() routine that takes an
  extra direction argument.  bd_read() and bd_write() are now simple
  wrappers around bd_io().
- If a disk supports EDD then always use it rather than only using it if
  the cylinder is > 1023.  Other parts of the boot code already do
  something similar to this.  Also, GPT just uses LBAs, so for a GPT disk
  it's probably best to ignore C/H/S completely.  Always using EDD when
  it is supported by a disk is an easy way to accomplish this.

aa785996fd - Make better use of the global chosen, memory and mmu handles instead
of obtaining them over and over again and pretending we could do
  anything useful without them (for chosen this includes adding a
  declaration and initializing it in OF_init()).
- In OF_init() if obtaining the memory or mmu handle fails just call
  OF_exit() instead of panic() as the loader hasn't initialized the
  console at these early stages yet and trying to print out something
  causes a hang. With OF_exit() one at least has a change to get back
  to the OFW boot monitor and debug the problem.
- Fix OF_call_method() on 64-bit machines (this is a merge of
  sys/dev/ofw/openfirm.c rev 1.6).
- Replace OF_alloc_phys(), OF_claim_virt(), OF_map_phys() and
  OF_release_phys() in the MI part of the loader with wrappers around
  OF_call_method() in the sparc64. Beside the fact that they duplicate
  OF_call_method() the formers should never have been in the MI part
  of the loader as contrary to the OFW spec they use two-cell physical
  addresses.
- Remove unused functions which are also MD dupes of OF_call_method().
- In sys/boot/sparc64/loader/main.c add __func__ to panic strings as
  different functions use otherwise identical panic strings and make
  some of the panic strings a tad more user-friendly instead of just
  mentioning the name of the function that returned an unexpected

Shift to using == rather than < or > for calculating the timeout,

304d0536ab All SD cards have a block size of 512. The READ_BL_LEN field in the
CSD is usually 512 (well, 9), but for 2GB (and the rogue 4GB SD cards)
it is 1024 (or 2048 for 4GB).  This value doesn't work for the block
read commands (which really want 512).  Hardcode 512 for those.  This
may break really old MMC cards that don't have a 512 block size (I've
never seen one: make my day and send me one :-), but since the MMC
side of the house is currently broken, it should only have the effect
that 2GB (and non-conforming 4GB) SD cards will work.

My 'non-conforming' 4GB SD card also works now too.  The
non-conforming 4GB SD cards were sold for a while before the SD
association was worried they would be (a) incompatible (different FAT
flavor on them) and (b) confusing for the new SDHC standard and
cracked down on suppliers' bogus use of the SD trademark...

their disk read routine.
