build/release/src: Include U-Boot sources in source archive

2022-12-10T12:40:11+00:00

Add U-Boot to the source release script's modules list so that it is
included in source release tarballs. Don't include the unused upstream
source and .git directories.

build/clean: Add helper script to clean U-Boot builds

2022-12-10T12:39:33+00:00

Copy the resources/scripts/build/clean/crossgcc script and adapt it to
run "make distclean" on U-Boot build trees. Some build artifacts persist
after the run, so also run "git clean -fdx" if we can.

dependencies/debian: Install dependencies for U-Boot

2022-12-10T11:19:00+00:00

U-Boot build dependencies are listed on their online documentation [1],
but the listed Debian packages also include test-only dependencies.
While installing dependencies, install the packages necessary to build
U-Boot, except for the test-only ones I could identify.

build/roms: Support using "u-boot" ELF file as U-Boot payload

2022-12-10T11:19:00+00:00

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.

build/roms: Don't rebuild crossgcc if it was already built

2022-12-10T11:19:00+00:00

The roms_helper script skips building crossgcc-i386 if its target
directory exists. Skip it for other architectures as well.

build/roms: Make coreboot crossgcc usable for payloads and modules

2022-12-10T11:19:00+00:00

Add the coreboot-built cross-architecture toolchains to the PATH so that
modules and payloads can use them. When building for a foreign-arch
board, also export CROSS_COMPILE pointing to the appropriate prefix.

build/roms: Build 32-bit crossgcc for AArch64 as well

2022-12-10T11:19:00+00:00

This re-applies commit a69855f7e448 ("Build 32-bit crossgcc for AArch64
as well") which was inexplicably reverted along with unrelated changes.
Mention in a comment that building crossgcc-arm is necessary for
AArch64.
