Set default U-Boot revision to v2023.01 and rebase patches on top of
that. Upstream kconfig status is a bit unstable, so updating configs
with `make oldconfig` would miss important upstream changes.
For each board, run `make savedefconfig` and `diffconfig -m` at the old
version to get a diff from upstream defconfigs. Fix those affected by
upstream changes, like SYS_TEXT_BASE being renamed to TEXT_BASE. Then
append those to the new version's defconfigs and run `make olddefconfig`
to get updated configs.

The USB 2.0 ports on Exynos boards need the relevant driver enabled by
USB_EHCI_EXYNOS. This is enabled by default depending on USB_EHCI_HCD.
It's already enabled on snow and spring, but apparently not on peach
boards, as discovered from other people's attempts to enable it [1][2].
Enable it also on the peach_pi and peach_pit.

Further, they were enabling VGA ROM execution in coreboot, but
this should be handled by SeaBIOS.
This board should not have a GRUB payload enabled either; this
will be checked and fixed if necessary in the next commit.

Add a build for QEMU AArch64 virtual machine using U-Boot as payload.
Coreboot config is based on the following defconfig:
CONFIG_CBFS_SIZE=0x00c00000
CONFIG_BOARD_EMULATION_QEMU_AARCH64=y
CONFIG_CONSOLE_CBMEM_BUFFER_SIZE=0x20000
CONFIG_COREBOOT_ROMSIZE_KB_12288=y
CONFIG_UART_PCI_ADDR=0x0
The resulting ROM can be booted with a command line like:
qemu-system-aarch64 \
-machine virt,secure=on,virtualization=on \
-cpu cortex-a53 -m 1G \
-vga none -display none -serial stdio \
-bios bin/qemu_arm64_12mb/uboot_*.rom
However, this is little more than a proof of concept because U-Boot
upstream is missing coreboot integration on non-x86 boards, which could
have been useful for e.g. a framebuffer.

Add a U-Boot payload build for the QEMU AArch64 virtual machine. The
config is same as upstream "qemu-arm64" defconfig, but SYS_TEXT_BASE is
set to 0x50000000 so that it doesn't conflict with coreboot. QEMU
auto-generates and passes a device-tree file to U-Boot at runtime,
there's no compile-time canonical version, so there's no need to set
REMAKE_ELF or OF_EMBED.
It's not immediately obvious if QEMU-specific drivers are available to
support display output, but most coreboot integration is unavailable
(depends on x86) and entire video subsystem is disabled in the U-Boot
upstream defconfig.

U-Boot runtime configuration is done with a device-tree file, which is
built alongside the executable in the upstream build system, and must be
available to U-Boot at runtime.
This device-tree is normally not linked into the default "u-boot" ELF
file. So far we have been handling it by re-creating a "u-boot.elf" from
the raw binary parts by setting REMAKE_ELF, and using that as the
coreboot payload. Unfortunately, that fails to build for x86 boards,
more specificly the "coreboot" boards upstream.
It's also possible (but discouraged) to set OF_EMBED to embed the
device-tree file into the U-Boot itself, in which case we could use the
"u-boot" file as the payload on the "coreboot" boards. Add support for
using the "u-boot" file as the payload if "u-boot.elf" doesn't exist.

this is a hangover from pre-osboot-merge libreboot. the idea
was to distribute fsdg uboot archives
lbmk has uboot support, and releases will simply
include uboot in the main src archive like with everything else
the --nuke option in ifdtool will be used instead, to nuke
the ME regions in specific rom sets (and cbfstool will be
used to delete mrc.bin files from rom sets)
the new method being implemented is heavier on disk io, but
simplifies lbmk, and disk io could still be optimised in
the following ways:
* when copying roms from boards with ME in them, use
ifdtool --nuke to get filename.rom.new, and *move* (not copy)
filename.rom.new to the new destination (for use with tar)
* possibly modify ifdtool to make efficient use of mmap for
disk i/o; it currently loads entire roms into an allocated
buffer in memory
New x230edp_12mb target uses the
https://review.coreboot.org/c/coreboot/+/28950 patchset to add an
X230_EDP target to the default coreboot branch.
Consequently the "fhd" coreboot branch is no longer needed and has
been safely removed.
the intended use-case scenario was one in which vga rom initialisation
would be used, on desktop configurations, but without coreboot itself
handling vga rom initialisation, instead leaving that task to seabios
it was assumed that grub, when running on the bare metal with
build option "--with-platform=coreboot" would be able to display
like this, but it is not so when tested
in such setups (add-on gpu with grub payload), it is necessary to
extract the video bios and insert it into the coreboot rom, having
coreboot handle such execution. this is beyond the scope of lbmk,
in context of automated building, because we cannot reliably predict
things such as PCI IDs
do away with this build option entirely, for it does not serve the
intended purpose. it will be necessary to run PC GRUB instead (build
option --with-platform=i386-pc). PC GRUB can still read from CBFS,
and you could provide it as a floppy image file inside CBFS for
SeaBIOS to execute. in this setup, GRUB would function as originally
intended by the seabios_withgrub option; such a configuration is
referred to as "SeaGRUB" by the libreboot project, and experimentation
was done with it in the past, to no avail
it's better to keep things simple, in the libreboot project. simpler

In recent coreboot versions, running distclean started to erase the
cbfstool binary we built earlier in the util/cbfstool dir via the
cbutils build script call. The coreboot build puts it in a different
directory, and the roms build script can't find it when trying to add
payloads to the roms. This doesn't make the script fail (because set -e
is stupid like that), and the build appears to succeed if you don't look
close enough to see the "cbfsutil not found" error.
Build the coreboot utils we want at the places we want them after
calling distclean, so that we can actually use cbfsutil and avoid
silently-broken roms with newer coreboot versions.

This enables embedding U-Boot into the coreboot roms as the payload. For
now, the ELF file generated by enabling CONFIG_REMAKE_ELF is used, which
includes the U-Boot binary and the board-specific device-tree file. It
might be better to use the FIT payload support for U-Boot, but that was
reportedly broken and is not tested yet.
Coreboot boards can specify payload_uboot="y" in their board.cfg to
enable building a rom with U-Boot as the payload, which is built from
the U-Boot board with the same name. Boards can further specify a
uboot_config option, to choose which board-specific config file U-Boot
should be built with.

This enables building U-Boot for boards which have config files in
resources/u-boot, and copying built files that could be usable to make
coreboot payloads. Right now, there is no such board in this repo.
The most important file here is "u-boot.elf", which is a combination of
the U-Boot binary and the appropriate device-tree file for the board.
Building this needs CONFIG_REMAKE_ELF=y on the U-Boot part, and using
this with CONFIG_PAYLOAD_ELF=y on the coreboot build works fine.
Note that this isn't enough to make U-Boot-only releases, since
low-level prerequisites like arm-trusted-firmware aren't passed in to
the U-Boot build system. Coreboot builds its own copy of TF-A and sets
it up on the board, so using these U-Boot builds as payloads should
still work.

Keeping the git repositories is useful while development, e.g. to avoid
git cloning repositories over and over again while debugging download
scripts. Setting the NODELETE environment variable keeps the blobs and
the git repositories. Allow a slightly finer-tuned version of this where
we can keep only the git-related files by setting the variable to "git".

Boards may want to specify a board-specific U-Boot revision. At the very
least, pseudo-boards for u-boot-libre releases will need to specify their
U-Boot versions somehow.

The U-Boot download script is designed to help with releasing
u-boot-libre and it can only prepare a generic U-Boot v2021.07 tree.
However, we will need to build board-specific versions of U-Boot to be
able to use it as a coreboot payload effectively.
As a first step toward that, make the download script prepare per-board
copies of U-Boot v2021.07. Then, add a 'v2021.07' pseudo-board for the
u-boot-libre release script to work on.

The u-boot-libre tarball contents' mtimes are an unconventional value
due to timezone confusion. For reproducibility, timestamps like these
are usually set by a SOURCE_DATE_EPOCH which is respected by both

and properly set the mtimes to the Unix epoch when it's not defined.

This doesn't change the existing usage of the scripts:
- For the Coreboot script, before this change, all arguments that were
passed were considered as board to download the Coreboot source code
for.
Here we added the '--help' and '--list-boards' arguments, so it
should not be an issue as it is extremely unlikely that a board
would be called '--help' or '--list-boards'.
- All the other scripts don't use any arguments so passing --help
should not conflict with the existing usage.

Many people using FSDG compliant distributions or wanting to use one
are already familiar with linux-libre. This change renames the
resulting tarball to u-boot-libre to make it easier for people to
understand the goal of this tarball.
In addition we also rename the version from v2021.07 (which is the git
tag corresponding to the release) to 2021.07 as u-boot upstream
tarballs use that.

Once the tarball are released, it will enable distributions to use
these tarballs to produce deblobbed u-boot packages.
Note that the produced tarball is not reproducible yet. Because of
that it has to be trusted.
During a release, it's a good idea to sign the uncompressed tarball as
the various compression formats and associated tools make different
tradeoffs.
For instance with xz, xz -9e tends to compress really well with the
the most used xz[1] implementation, and most GNU/Linux users probably
already have it installed, but and the drawbacks is that the format is
very fragile[2].
The lzip format is more suited for long term archiving but its most
packaged implementation[3] is less likely to be already installed by
users than more well known formats like xz, bzip2 or gzip.
Being able to add more compression formats after the release is also
useful, for instance to accommodate different build systems or use
cases (like being able to build u-boot with less dependencies in
distributions like Guix, or building u-boot directly on devices which
don't have enough RAM for xz for instance).

Coreboot is enabling PECI on these CPUs which, according to Intel erratum, must

that the feature is supported. In any case, belgin on IRC found the commit in

reverting coreboot's PECI patch.
