in some cases, use of x_ or xx_ can be error-prone,
due to the way $@ is handled; commands requiring
quotes, or with funny file names as arguments such
as spaces in the file name, or other special
characters, can make the x/xx functions break.
in those cases, where x/xx must not be used, the
commands use || err instead
in other cases, use of x/xx is superfluous, and has
been removed in some commands.

recent build system simplifications have enabled
this change, thus:
./build fw coreboot -> ./build roms
./build fw grub -> ./build grub
./build fw serprog -> ./build serprog
./update project release -> ./update release
./update project trees -> ./update trees
./update vendor download -> ./vendor download
./update vendor inject -> ./vendor inject

i previously added this just for kicks, but it's not
actually needed; gnat isn't used on fam15h boards so
lbmk doesn't even use it (it's disabled).
in fact, i tested lbmk with crossgcc_ada handling
taken out, but with said patch; i still got build
errors with gnat anyway, on that old coreboot
revision (but gnat isn't needed there anymore).

We don't really need a custom coreboot tree for Chromebooks. I had added
one, because at a cursory glance to the available config/coreboot/board
subdirectories I had the impression that I should. But upstreams have
one tree for every board and I think we should move towards that too.
Move the one important BL31 makefile patch into the default coreboot
patches, update the gru boards' configs by running savedefconfig in the
cros tree and then running olddefconfig in the default tree.

By default U-Boot stores EFI variables in a ubootefi.var file in
whatever EFI System Partition it finds, which would be a FAT filesystem.
I'm occasionally finding out while testing that my ESPs somehow end up
with a corrupted filesystem, and I'm suspecting it's this.
For now, disable storing EFI environment variables on disk so that
U-Boot doesn't try to manipulate the filesystem.
Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
Enable U-Boot commands to manipulate EFI environment storage, to
self-test EFI implementation, and to run a basic EFI test application.
These are so that we can test and debug EFI functionality easier.

Normally U-Boot immediately resets the board on a panic. I had run into
"Synchronous Abort"s from shim and rEFInd, and having a traceback in
those cases can be useful. Hang instead of resetting, so the panic
reason stays on the screen.

U-Boot can keep a "copy" framebuffer to read from, for devices where
reading from hardware framebuffer is expensive. This needs the video
driver to support it. The Rockchip video driver doesn't need or support
it, so this option does nothing on gru boards. Disable it.

U-Boot upstream used to have 16KB for EFI variables, and this was
causing problems with shim. Commit f0236acbc6 ("u-boot: Increase EFI
variable buffer size") fixed this by raising it to 32KB in our builds.
It has now been raised to 64K upstream, so raise it here as well.

For Rockchip boards U-Boot tries to build SPI and MMC images that
require an externally built BL31 file to be provided, and the build
fails otherwise. This is not really as configurable as it should be.
In Libreboot, we only care about the build outputs for U-Boot proper.
There is a BL31 built during our coreboot builds, but using that in
U-Boot builds is a chicken-and-egg problem. Building BL31 outside the
coreboot build and passing it to both projects is possible, but needs
work.
For now, stop trying to build these U-Boot-only images as a workaround,
by removing the binman image descriptions from the device-tree sources.
Additionally, disable in our configs the BINMAN_FDT functionality that
allows using these at runtime as it requires them to be present.

Set default U-Boot revision to v2023.01 and rebase patches on top of
that. Another series about 16x32 fonts was merged upstream, so drop some
now-unnecessary patches we had for that. For the video damage tracking
series, switch to the version I'm trying to upstream.
Upstream kconfig status is a bit unstable, so updating configs with
`make oldconfig` would miss important upstream changes, since they rely
on carrying defaults via upstream defconfigs. Update the configs as
such:
- Turn old configs into defconfigs (./update project trees -s u-boot)
- Save the diff from old upstream defconfig (diffconfig $theirs $ours)
- Update U-Boot revision, rebase patches, and clean old trees
- Prepare new U-Boot tree (./update project trees -f u-boot)
- Review the diffconfigs to see if any options were renamed upstream
- Copy over the new upstream defconfigs and apply earlier diff
- Turn new defconfigs into configs (./update project trees -l u-boot)

Add an "-s" flag for "make savedefconfig", "-l" for "make olddefconfig"
and "-n" for "make nconfig" to the update script. The first two are
mainly useful for U-Boot, to compare our configs to the upstream
defconfigs and stay in sync with any upstream changes. The latter is
because the ncurses one has a nice "Symbol Search" that can point out
the menu entry for a config symbol we know.

The "u-boot.bin" file generated by U-Boot builds is a raw binary. When
adding payloads to a CBFS, we need to use ELF files with add-payload
or manually pass the entry point and load address of the payload binary
with add-flat-binary.
We primarily use the "u-boot.elf" which gets build with the REMAKE_ELF
option, as it also has the necessary device-tree binary that U-Boot
usually needs to work. When the option is not set (e.g. for QEMU), we
need to use the "u-boot" file which is an ELF.

e.g. src/coreboot/coreboot must not appear in a release,
because we instead have directories like

with --mtime, files added to the archive can be set
to a static date (in this case, the unix epoch)
the one used here is derived from git commit dates,
and it is static; if not being handled in lbmk.git,
the versiondate file never changes
this is the first patch in a series of patches designed
to bring about reproducible builds in libreboot
a solution will need to be found, for non-GNU tar
implementations, because they did not have an
equivalent option according to their manpages.
for example, BSD tar implementations.
perhaps i could systematically go around changing
file dates, on each file, as a fallback behaviour?

this way, the src tarball is guaranteed to be clean.
the downside is that lbmk itself does not currently
handle crossgcc downloads, and there may be some
stragglers such as third party modules automatically
downloaded by certain codebases that libreboot uses.
