By making lbmk fully POSIX-compliant, it will be easier to port lbmk to
other systems implementing POSIX such as Alpine Linux and FreeBSD.

due to upstream bloat, these no longer fit. it will have to be
fixed in the next libreboot release
|
|
|
|
memtest can't fit in such tiny space alongside SeaBIOS
|
|
|
|
The configs were enabling SeaBIOS payload, but this is to be
handled by lbmk, not coreboot.
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 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.

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.

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.

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 doesn't run on this board when this SuperIO serial driver is

Add a U-Boot build for the qemu_x86_12mb board. The config is a copy of
the upstream "coreboot" defconfig, but with OF_EMBED=y.

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.

Add a series posted to upstream mailing lists that makes the GRUB
text-mode console faster by implementing video damage tracking [1].
Refresh the config files to include its new VIDEO_DAMAGE Kconfig.
Patch 7/7 upstream has a tiny conflict with "Improve UEFI experience"
series we already have, but it's only in the diff context. No changes
other than fixing that.

Merge all boards into a common "default" tree, currently for v2022.07.
This ends up applying the "Improve UEFI experience on DM_VIDEO" series
to everything, so refresh the configs for the new options.

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.

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.

When overriding which payloads will be built with the -p command line
argument, the roms_helper script builds the Memtest86+ payload before
checking if it should be disabled. Move the build command after the
command line override.

The U-Boot download script does its work from the repository root
instead going into the newly created dirs, unlike the coreboot
counterpart. It should run the board-specific extra.sh files with the
downloaded paths as their working directory. Do so by a subshell.

The no-argument form of the U-Boot download script prepare trees for all
boards when run with no arguments, like the corresponding script for
coreboot. The usage text for this case was removed without any changes
to the corresponding code, assume it was by mistake and add it back.

Removing the git dirs was part of deblobbing, which Libreboot no longer
cares about. The variable that triggers it is no more. Remove the dead

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
|
|
e.g.
./ifdtool --nuke me coreboot.rom
this will be used by rom release build scripts, to scrub
stuff like intel me from the rom

These boards are near-identical, this appears to suffice.

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
for users, that is
