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
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
for users, that is
buggy, buggy, buggy, buggy, buggy, buggy, buggy
full of bugs, these boards never worked properly. i got ripped
off with these.
now i'm ripping off the band aid
use dasharo if you want d16 stuff. i'm done with it.
python2 is eol and the only thing that needed it was build scripts
inside tianocore, back in osbmk days when tianocore was supported
in the (osboot) build system. nothing else requires it, so chuck it
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.

The code that compiles coreboot crossgcc changes the working directory
to the coreboot directory, and the following code cannot find the lbmk
scripts that it needs to run. Compile ARMv7 and AArch64 cross compilers
in a subshell like in the x86 case so the rest of the script can work.

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.

Downloading coreboot and U-Boot takes quite the disk space and bandwith.
We don't need to download entire repos, only the revisions that we are
interested in.
Use the --depth=1 option to only download the files we need. Since the
initial clones may not have our target revision, always try to fetch it.

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.
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 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
coreboot and U-Boot. Use it in the u-boot-libre release script as well,
and properly set the mtimes to the Unix epoch when it's not defined.
