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

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.
this will have to be audited later (and it will be).

coreboot closely matches upstream, whose current release

under the current logic, errno would be ECANCELED
if neither checksum is valid, or I/O related if
pwrite fails; alternatively, the for loop exits
and the file has been written, where it is quite
correctly reset already.
ergo, the errno reset at the start of
writeGbeFile is superfluous. remove this bloat.

This updates lbmk's copy of e6400-flash-unlock to commit c5567fece479
(README.md: Update with info about broader device support) in my
upstream repo.
Changes:
- Theoretical support for any Dell system that implements that flash
descriptor override command. This is done by reading base address
registers at runtime instead of hard coding them for specific devices.
Tested on the Latitude E6400 and Latitude E6430.
- Support for OpenBSD. It compiles, runs, and behaves as expected,
though I have not actually tested internally flashing with flashrom
yet. It should work though, as the program checks if the descriptor
override is set and the BIOS Write Enable is able to be set to 1, which
is all that is needed to internal flash.
- Integrated changes made in the lbmk copy
- Moved operating system accessor implementations to their own file
It should be fully functional, though minor formatting and cleanup
changes are still planned.

some users reported build errors. technically, there's
nothing wrong with lbmk but it relies on hostcc, and
hostcc is hit or miss when it comes to cross compiling
32-bit, depending on the build system of whatever project.
lbmk needs to handle cross compilation. for now, i'm just
disabling memtest86plus on non-64-bit hosts.

The logic has been re-written, where source archives are
concerned. This clones the current repository, and starts
a new build from scratch. A custom release directory is
possible, by passing -d
This eliminates a step during build-testing, saving hours
of time, because it builds the release archive *inside* the
release archive, with git files removed, thus replicating
the same setup that the user would have.
This also makes everything a bit more consistent, because
it's guaranteed that a release archive will always have
the same files; previously, the release build script would
only copy what was already built, without building anything.
Now, this script builds everything itself.
The script also builds serprog images, not just coreboot.
Usage:
./update project release
If -d is not passed, release/ is used inside lbmk.
Otherwise, you could do:
./update project release -d /path/to/directory
If the directory exists, this script will exit (error).
Other minor fixes: build/fw/coreboot: make version in
coreboot-version (file) not contain hyphens, to work
around a quirk in coreboot's build system when not building
on regular libreboot releases. this quirk only appears
when lbmk is not being compiled under git.
The other main benefit of this change is that the new
script will probably require a lot less maintenance.

the script used to be called once per target, now it
handles every target. the grub background image wasn't

Just one script.
Just one!
Well, two, but the 2nd one already existed:
logic in update/project/trees and
update/project/repo was merged into
include/git.sh and update/project/build
was renamed to update/project/trees; an -f
option was added, which calls the functions
under git.sh
so git clones are now handled by the main build
script (for handling makefiles and defconfigs)
but the logic there is a stub, where git.sh
does all the actual heavy lifting
this cuts the file count down by two, and reduces
sloccount a reasonable amount because much of
the logic already exists in the build script, when
it comes to handling targets. git.sh was adjusted
to integrate with this, rather than act standalone
