For some reason, 32-bit U-Boot only works when executed from
GRUB, but not SeaBIOS; 64-bit U-Boot only works from SeaBIOS!
This will have to be investigated. Standalone U-Boot, where
U-Boot is the primary payload, has not yet been tested in
Libreboot, and will not be provided for some time due to
stability concerns. More testing is needed!

Currently seems to stall when booted from the GRUB
payload, but works when booted from the SeaBIOS menu.
I also tested it as a standalone payload and it seems
to boot. Will test on hardware next, and start adding
it to more mainboards.

NOTE: Support added for xarch target x86_64-elf,
but U-Boot failed to build with this error:
OBJCOPY lib/efi_loader/helloworld.efi
x86_64-elf-objcopy: lib/efi_loader/helloworld_efi.so: invalid bfd target
make[2]: *** [scripts/Makefile.lib:476: lib/efi_loader/helloworld.efi] Error 1
Since I'm building U-Boot for x86_64 *on* an x86-64
host, and since that is currently the recommended type
of machine to use for cbmk development, and since the
other x86 payloads currently don't cross compile anyway,
this is an acceptable compromise for now. This is because
at present, I'm not making U-Boot the primary payload on x86,
instead preferring to chain it from GRUB and SeaBIOS.
The target.cfg file for x86 u-boot shows xarch/xtree commented.
Uncomment these to compile on crossgcc instead of hostcc.
I mention 64-bit because I initially did this first, but decided
to do 32-bit first. I'll work on the 64-bit one next (SPL).
It's only enabled in QEMU for now.

instead, make it a helper function, defined in target.cfg
this means that we can also do the same with other projects
in the future, and it is expected that we will have to.
these helper functions are used in cases where we want
additional actions to be performed.
actually, the helper could be anything. for example, you
could write:
mkhelper="./build foo bar"

the background is only a few kb. the whole rationale
before was to limit the space used in memdisk, but this
decision was made when the background was much bigger;
it has since been optimised greatly, and the grub modules
were heavily reduce, so it should be safe.
grub's memdisk breaks when you add too much data to it.
as part of simplifying the rest of lbmk, this change removes
some more bloat from the rest of lbmk. handling this in the
memdisk is much simpler than handling it with cbfstool.

* nvme: contains nvme support
* xhci: contains xhci and nvme support

The xHCI patches were removed because they caused issues
on Sandybridge-based Dell Latitude laptops. See:
https://codeberg.org/libreboot/lbmk/issues/216
The issue was not reported elsewhere, but we still don't
need xHCI support in Canoeboot's GRUB because none of the
available coreboot targets have xHCI support. However, we
may want it in the future and it helps to keep Canoeboot
in sync with Libreboot (this patch is adapted from lbmk).
Each given coreboot target can say which GRUB tree to use
by setting this in target.cfg:
grubtree="xhci"
In the above example, the "xhci" tree would be used. Some
generic GRUB config has been moved to config/data/grub/
and config/grub/ now looks like config/coreboot/ - also,
the grub.cfg file (named "payload" in each tree) is copied
to the GRUB source tree as ".config", then added to GRUB's
memdisk in the same way, as grub.cfg.
Several other design changes had to be made because of this:
* grub.cfg in memdisk no longer automatically jumps to one
in CBFS, but now shows a menuentry for it if available
* Certain commands in script/trees are disabled for GRUB,
such as *config make commands.
* gnulib is now defined in config/submodule/grub/, instead
of config/git/grub - and this mitigates an existing bug
where downloading gnulib first would make grub no longer
possible to download in lbmk.
There is another reason for merging this design change from
lbmk, and that reasoning also applies to lbmk. Specifically:
This change will enable per-board GRUB optimisation in the
future. For example, we hardcode what partitions and LVMs
GRUB scans because * is slow on ICH7-based machines, due
to GRUB's design. On other machines, * is reasonably fast,
for automatically enumerating the list of devices for boot.
Use of * (and other wildcards) could enable our GRUB payload
to automatically boot more distros, with minimal fuss. This
can be done at a later date, in subsequent revisions.

in practise, the machines we support don't have
the option of including so many disks; 8 seems like
the most reasonable default. additionally, it's
unreasonable to expect *20 partitions*
this hardcoding is done to avoid using *, which is
slow in grub on some machines (the grub kernel always
re-enumerates the devices during every operation,
without caching any of it)
yet, the hardcoding is also slow; balance it a bit
better by searching fewer permutations, but not so few
that it would likely break a lot of setups
Signed-off-by: Leah Rowe <leah@libreboot.org>
we already supported syslinux but not grub
support grub by scanning for the most common paths,
based on the most popular distros
we don't hardcode this with * because it slows down
the boot, and in practise many distros still use the
same grub.cfg location as in BIOS systems (the EFI
one is often just a link to the BIOS one)

the path "/boot/EFI" is unnecessary because the ESP

Previously, grub_scan_disk could set ata, ahci or "both",
which would make both be tried (ahci first). This worked
when we only dealt with ata and ahci devices, but now we
support nvme devices so the logic is inherently flawed.
Instead, use grub_scan_disk to store the boot order, e.g.:
grub_scan_disk="ahci nvme ata"
grub_scan_disk="nvme ata"
In the first example, it would make GRUB scan ahci first,
then nvme and then ata.
In the secontd example, it would make GRUB scan nvme first,
and then ata.
If "both" is set, or anything other than ahci/ata/nvme,
grub_scan_disk is now changed to "nvme ahci ata".
Actual grub_scan_disk entries in target.cfg files will now
be modified, to match each machine.

Well, fix is the wrong word. We want xHCI ideally.

There is no need to add multiple keymap files, because
GRUB can load keymaps from CBFS. The current build logic
is designed to avoid building multiple GRUB binaries,
which are expensive computationally because each one
would then have to be compressed for each board.
This patch provides the best of both worlds: less space
used in flash like in the old lbmk design (1 keymap per
board), but retaining the current build speeds and therefore
not re-introducing the slowness of lbmk's previous GRUB
build logic.
The grub.cfg file has been modified, accordingly. It now
only loads a keymap.gkb file from CBFS, by default. It does
this, only if that file exists; if not, GRUB already defaults
to US Qwerty layout anyway.
ALSO: compress all keymap gkb files with xz -6
GRUB automatically decompresses files when accessed.
This results in about 2KB of flash space saved in CBFS.
Here is real-world data, showing the increased flash space:
< fallback/payload 0x3eb80 simple elf 548821 none
< keymap.cfg 0xc4bc0 raw 16 none
< (empty) 0xc4c00 null 11633316 none
---
> fallback/payload 0x3eb80 simple elf 546787 none
> keymap.gkb 0xc43c0 raw 344 none
> (empty) 0xc4540 null 11635044 none
This was taken by diffing the cbfstool "print" output,
both before and after. The *after* result is with this change.
11633316. In this example, 1728 bytes have been saved. Therefore,
with compression taken into account, this patch saves about 1.7KB
of space in CBFS.
This change means that lbmk can now scale to support hundreds
of keymaps, without increasing the amount of flash space used,
in each given image. Since the keymap files are compressed in
lbmk.git, in advance, we spend no additional time on compression
at build time. The resulting change in build speed in negligible.
Adding your own keymap.gkb file was already possible, for changing
the keymap in libreboot images, if you didn't want to change the
memdisk (and thus re-compile grub.elf). Now, this is the default
behaviour, and the only way to do it. It's much more efficient.
The original keymap files can be restored, by running unxz.

cbmk 9429287 is the present canoeboot revision, on this day,
two commits after canoeboot 20231107
the cbmk revision was based on lbmk c4d90087, but lbmk
has developed a lot since, right up to f5b04fa5. lbmk
c4d90087 was four commits after libreboot 20231106
this patch brings cbmk up to date, versus lbmk f5b04fa5,
which is 135 commits after libreboot 20231106 (not 4)
therefore, the next canoeboot release shall import lbmk
changes made *after* lbmk revision f5b04fa5. good day!
In English (the above is for my reference, next time
I make a new canoeboot release):
This imports all of the numerous improvements from
Libreboot, sans the non-FSDG-compliant changes. You
can find a full list of such changes in the audit4 page:
https://libreboot.org/news/audit4.html
A full canoeboot-ised changelog will be available in
the next canoeboot release, with these and subsequent
changes. Most notable here is the update to the new
GRUB 2.12 release (instead of 2.12-rc1), and the
improvements Riku made to pico-serprog. And the build
system improvements from lbmk, such as improved, more
generic cmake and autoconf handling.
Canoeboot-specific changes: I also tweaked the deblob
logic, to make it less error-prone. The new design
changes imported into cbmk (based on latest lbmk) somewhat
broke the deblob logic; it was constantly reminding the
user that blobs.list was missing for coreboot,
at config/coreboot/blobs.list - coreboot is a multi-tree
project in both cbmk and lbmk, and the deblob logic was
tuned for single/multi, but was treating coreboot as both.
for simplicity, i removed the check for whether blobs.list
is present. this means that the operator must ensure that
these files are present, in any given revision, where they
are required on a given set of projects (and the files are
all present, in this update to cbmk)
Also of note: the grub.cfg improvements are included in this
cbmk update. The improved grub.cfg can find grub/syslinux
configs by default, not just grub anymore, also finds extlinux,
and will also find them on EFI System Partition - in addition,
UEFI-based install media is also more robust; although cbmk
doesn't provide UEFI configurations on x86, our GRUB palyoad
does still need to work with distro install media, and many
of them now use UEFI-based GRUB configurations in their
installation media, which just happen to work with our GRUB
