a problem on 32-bit systems which have ram occupying the end of the physical
address space -- for example, a block of ram at 0x80000000 with a size of
0x80000000 was overflowing 32 bit math and ending up with a calculated size
of zero.
This is a fix for one of the two problems mentioned in the PR. Something

PR: 201614
providing compiled-in static environment data that is used instead of any
data passed in from a boot loader.
Previously 'env' worked only on i386 and arm xscale systems, because it
required the MD startup code to examine the global envmode variable and
decide whether to use static_env or an environment obtained from the boot
loader, and set the global kern_envp accordingly. Most startup code wasn't
doing so. Making things even more complex, some mips startup code uses an
alternate scheme that involves calling init_static_kenv() to pass an empty
buffer and its size, then uses a series of kern_setenv() calls to populate
that buffer.
Now all MD startup code calls init_static_kenv(), and that routine provides
a single point where envmode is checked and the decision is made whether to
use the compiled-in static_kenv or the values provided by the MD code.
The routine also continues to serve its original purpose for mips; if a
non-zero buffer size is passed the routine installs the empty buffer ready
to accept kern_setenv() values. Now if the size is zero, the provided buffer
full of existing env data is installed. A NULL pointer can be passed if the
boot loader provides no env data; this allows the static env to be installed
if envmode is set to do so.
Most of the work here is a near-mechanical change to call the init function
instead of directly setting kern_envp. A notable exception is in xen/pv.c;
that code was originally installing a buffer full of preformatted env data
along with its non-zero size (like mips code does), which would have allowed
kern_setenv() calls to wipe out the preformatted data. Now it passes a zero
for the size so that the buffer of data it installs is treated as
non-writeable.
libstand is built in three places (lib/libstand, sys/boot/libstand32,

Anyway, the logic has been tweaked a little to get the easier bits

it from the uboot net_init() implementation. The routine uses the standard
U-Boot env vars plus a freebsd-specific variable named "rootpath" (the
corresponding u-boot variable for that would be "bootfile" except that it
refers to ubldr, so a new name was needed to communicate the path to ubldr).
This allows ubldr to load a kernel from nfs without requiring a dhcp or
bootp server to provide the server ip and rootpath parameters.
than bootp and rarp.
The code which splits a serverip:/rootpath string into rootip and a plain
pathname is now a separate net_parse_rootpath() function that can be
called by others. The code that sets the kernel env vars needed for
nfs_diskless is moved into net_open() so that the variables get set no
matter where the params came from.
There was already code in net_open() that allowed for the possibility that
some other entity has set up the network-related global variables. It uses
the rootip variable as the key, assuming that if it is set all the other
required variables are set too. These changes don't alter the existing
behavior, they just make it easier to actually write some new code to get
the params from another source (such as the U-Boot environment).
Previously, ubldr would use the virtual addresses in the elf headers by
masking off the high bits and assuming the result was a physical address
where the kernel should be loaded. That would sometimes discard
significant bits of the physical address, but the effects of that were
undone by archsw copy code that would find a large block of memory and
apply an offset to the source/dest copy addresses. The result was that
things were loaded at a different physical address than requested by the
higher code layers, but that worked because other adjustments were applied
later (such as when jumping to the entry point). Very confusing, and
somewhat fragile.
Now the archsw copy routines are just simple copies, and instead
archsw.arch_loadaddr is implemented to choose a load address. The new
routine uses some of the code from the old offset-translation routine to
find the largest block of ram, but it excludes ubldr itself from that
range, and also excludes If ubldr splits the largest block of ram in
two, the kernel is loaded into the bottom of whichever resulting block is
larger.
As part of eliminating ubldr itself from the ram ranges, export the heap
start/end addresses in a pair of new global variables.
This change means that the virtual addresses in the arm kernel elf headers
now have no meaning at all, except for the entry point address. There is
an implicit assumption that the entry point is in the first text page, and
that the address in the the header can be turned into an offset by masking
it with PAGE_MASK. In the future we can link all arm kernels at a virtual
address of 0xC0000000 with no need to use any low-order part of the
address to influence where in ram the kernel gets loaded.

Parameters and variables now use the cannonical typenames set up by elf.h
(Elf_Word, Elf_Addr, etc) instead of raw C types. Hopefully this will
prevent suprises as new platforms come along and use this code.
The function was renamed from _reloc() to self_reloc() to emphasize its
difference from the other elf relocation code found in boot/common.

loaded at boot time via the provided example in loader.conf. The tunable
'vm.blacklist' remains, but using an external file means that there's no
practical limit to the size of the list. This change also improves the
scanning algorithm for processing the list, scanning the list only once
instead of scanning it for every page in the system. Both the sysctl and
the file can be unsorted and contain duplicates so long as each entry is
numeric (decimal or hex) and is separated by a space, comma, or newline
character. The sysctl 'vm.page_blacklist' is now provided to report what
memory locations were successfully excluded.

The 'pwr' LED is connected to GPIO pin 35 (active high) and the 'act' LED
is connected to GPIO pin 47 (active high).
Remove the GPIO pin 47 from reserved pins list, previously it was used to
signaling the SD Card presence and now it is used by act LED.
This should be a non-functional change. A future change should
address the functional differences between these three and converge

It's necessary to reset the screen to make sure any vendor pixels are
gone when we start boot1. In the Lenovo X1 (3rd gen), this is the
only way to clear the screen. Previously, the Lenovo logo would only
disappear after the kernel started scrolling the display.
After resetting the screen, EFI could put us in the worst LCD mode
(oversized characters), so we now find the largest mode we can use and
hope it's the most appropriate one (it's not trivial to tell what's
the correct LCD resolution at this point). It's worth noting that the
final stage loader has a 'mode' command that can be used to switch
text modes.
While there, enable the software cursor, just like in the legacy boot
mode.

redzone below the stack pointer for scratch space and requires
interrupt and signal frames to avoid overwriting it. However, EFI uses
the Windows ABI which does not support this. As a result, interrupt
handlers in EFI push their interrupt frames directly on top of the
stack pointer. If the compiler used the red zone in a function in the
EFI loader, then a device interrupt that occurred while that function
was running could trash its local variables. In practice this happens
fairly reliable when using gzipfs as an interrupt during decompression
can trash the local variables in the inflate_table() function
resulting in corrupted output or hangs.
Fix this by disabling the redzone for amd64 EFI binaries. This
requires building not only the loader but any libraries used by the
loader without redzone support.
Thanks to Jilles for pointing me at the redzone once I found the stack
corruption.

(for example, a large mfsroot). Note that for EFI the kernel and
modules (as well as other metadata files such as splash screens or
memory disk images) are loaded into a statically-sized staging area.
When the EFI loader exits it copies this staging area down to the
location the kernel expects to run at.
- Add bounds checking to the copy routines to fail attempts to access
memory outside of the staging area. Previously loading a combined
kernel + modules larger than the staging size (32MB) would overflow
the staging area trashing whatever memory was afterwards. Under
Intel's OVMF firmware for qemu this resulted in fatal faults in the
firmware itself. Now the attempt will fail with ENOMEM.
- Allow the staging area size to be configured at compile time via
an EFI_STAGING_SIZE variable in src.conf or on the command line.
It accepts the size of the staging area in MB. The default size
remains 32MB.
