7df08a14e3 stand: Initial kboot support on amd64
Get amd64 compiling. However, the current kboot supports an old way of
enumerating memory and the new way needs to be incorporated as well. The
powerpc folks could use either, it seems and newer powerpc platforms
need some changes for kboot to work anyway.

This commit includes the linker script, trampoline code to start the new
kernel, Linux system calls and the necessary configuration glue needed
to build the binaries.

This includes a quick hack to get multiboot support, but we need to
really share these defines. The multiiboot2.h is the minimum needed to
build. We have multiboot information in three places now, so a
refactoring is in order.

This should be considered, at best, preliminary and experimental for
anybody wishing to try it out.

Turns out there is a libsa.3. It's a bit out of date, but we reference
it in a number of places so we should install it. We need to do the DO32
dance because this Makefile is included twice and we don't want it
installing twice.

914dc91d12 stand: zfs: handle holes at the tail end correctly
This mirrors dmu_read_impl(), zeroing out the tail end of the buffer and
clipping the read to what's contained by the block that exists.

This fixes an issue that arose during the 13.1 release process; in
13.1-RC1 and later, setting up GELI+ZFS will result in a failure to
boot.  The culprit is this, which causes us to fail to load geom_eli.ko
as there's a residual portion after the single datablk that should be
zeroed out.

cf8880d52b teken: color #3 is yellow not brown - use TC_YELLOW as the name
The console escape code standard (ECMA-48) specifies color #3 (escape
code 33) as yellow.  A brown console color is an artifact of the VGA
palette, which replaces dim (but not bright) yellow with brown.

e9249ef958 loader: accept "yellow" as a named color
For historical reasons console color number 3 may be either yellow (most
consoles) or brown (VGA palette).  The console escape code standard
uses "yellow", but teken color name constants appear to be based on the
VGA scheme and use TC_BROWN for color 3.  Even so, the palette table
used 50,50,0 as the RGB percentage tuple, resulting in a dim yellow for
framebuffer consoles at the time teken was introduced.

Amusingly, in 19e2ce2d83 the comment on the palette entry was changed
from "brown" to "dark yellow" but the colour itself was changed from
a pure yellow to being somewhat brown.

5c73b3e0a3 Add support for getting early entropy from UEFI
UEFI provides a protocol for accessing randomness. This is a good way
to gather early entropy, especially when there's no driver for the RNG
on the platform (as is the case on the Marvell Armada8k (MACCHIATObin)
for now).

If the entropy_efi_seed option is enabled in loader.conf (default: YES)
obtain 2048 bytes of entropy from UEFI and pass is to the kernel as a
"module" of name "efi_rng_seed" and type "boot_entropy_platform"; if
present, ingest it into the kernel RNG.

When the loader is verifying modules we already have a

5b13fa7987 ufs: Rework shortlink handling to avoid subobject overflows
Shortlinks occupy the space of both di_db and di_ib when used. However,
everywhere that wants to read or write a shortlink takes a pointer do
di_db and promptly runs off the end of it into di_ib. This is fine on
most architectures, if a little dodgy. However, on CHERI, the compiler
can optionally restrict the bounds on pointers to subobjects to just
that subobject, in order to mitigate intra-object buffer overflows, and
this is enabled in CheriBSD's pure-capability kernels.

Instead, clean this up by inserting a union such that a new di_shortlink
can be added with the right size and element type, avoiding the need to
cast and allowing the use of the DIP macro to access the field. This
also mirrors how the ext2fs code implements extents support, with the
exact same structure other than having a uint32_t i_data[] instead of a
char di_shortlink[].

c399283c71 Add an loader command on arm64 to sync the cache
On boot we don't need to perform any CPU cache management when the IDC
and DIC fields in the ctr_el0 register are set. Add a command to tell
loader to ignore these fields. This could be useful, for example, if the
hardware is misreporting the values and we are missing a quirk to enable
it.

It is not expected this will be needed, but is only intended as a
workaround to ensure the kernel can still boot.
