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!

it's important that we maintain realistic expectations.
x86 u-boot is not yet fully stable, so mark it as such.

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.

Of note: upstream has made several improvements to memory
management, and several fixes to file systems.
User-friendly change to LUKS: if the passphrase input failed,
the user is prompted again for the correct passphrase, instead
of GRUB just failing. Similar to cryptsetup luksOpen behaviour
under Linux.

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"
and it would do that (at the point of execution, PWD
is the root directory of the build system)

don't hardcode the check based on whether the current
project is grub. instead, define "btype" in target.cfg
if unset, we assume kconfig and permit kconfig commands
e.g. make menuconfig, make silentoldconfig, etc
this is to avoid the deadliest of sins:
project-specific hacks

this is bloat, because it's something the user can already
do at runtime configuration anyway.
set it to a reasonable default of 8 seconds instead of 5,
and don't honour the timeout variable in target.cfg.
this will be documented in the next release.

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.

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.
