U-Boot can be configured via environment variables which can be saved to
various storage devices. This usually defaults to MMC or SPI depending
on where it boots from, but assumes the device's layout is controlled by
U-Boot.
We should store the environment in SPI flash, but we also need to
configure coreboot FMAPs to reserve the area U-Boot would use as its
environment storage. For now, disable environment storage by setting
ENV_IS_NOWHERE=y to avoid overwriting random regions of SPI or MMC if
someone tries to save the variables.

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.

The display driver on the veyron boards needs reset drivers, more
specifically RESET_ROCKCHIP. This is enabled by default depending on
DM_RESET, which an upstream commit enables for veyron_jerry claiming it
fixes the display [1]. Enable it also in our configs, but for other
veyrons as well.

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.

Patch 7/7 upstream has a tiny conflict with "Improve UEFI experience"

Add a 'v2022.07' pseudo-board for the U-Boot download script with the

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).
