This adds U-Boot configuration for the Samsung Chromebook 2 13", also
known as "peach-pi" in the U-Boot upstream defconfigs. It uses the
shared tree for the "peach" baseboard. The config is almost the same as
upstream defconfig, but with REMAKE_ELF and POSITION_INDEPENDENT
enabled.
Untested since I don't have the peach pi chromebook. Note the there
doesn't seem to be any coreboot support for this chromebook.

This adds U-Boot configuration for the Samsung Chromebook Plus (v1),
also known as "chromebook_kevin" in the U-Boot upstream defconfigs. Also
adds a shared "gru" board directory to share with others having the same
baseboard.
It uses v2022.07 with some quality-of-life patches. The first one is a
clock adjustment to match coreboot clocks for the video output, the
second one is a series about text cursor support and larger fonts. These
are because the display has a high resolution of 2400x1600 at 12.3".
The config has the following diffconfig from the upstream defconfig for
this board:

Add a 'v2022.07' pseudo-board for the U-Boot download script with the
default blobs list, and mark the version as supported in u-boot-libre
release script.

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.
Copy the existing mechanism from download/coreboot for specifying
build info with board.cfg files. Specify the commit hash for the
'v2021.07' pseudo-board, and 'master' as the default.

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 deblob script hash ends up chaning due to copying my
author attribution from the download script, update its hash.

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).
