Leah Rowe dac9ea86d3 build/boot/roms: fail when build cbutils fails 2023-02-19 23:16:01 +00:00
Ferass 'Vitali64' EL HAFIDI f787044642 Do not rely on bashisms and behaviour undefined by the POSIX specification.
By making lbmk fully POSIX-compliant, it will be easier to port lbmk to
other systems implementing POSIX such as Alpine Linux and FreeBSD.

Alper Nebi Yasak 1c62b003ad build/roms: Support using "u-boot" ELF file as U-Boot payload
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.

Alper Nebi Yasak 5b6bf2a826 build/roms: Don't rebuild crossgcc if it was already built
The roms_helper script skips building crossgcc-i386 if its target

Leah Rowe 0c33438063 build/boot/roms: remove errant code 2022-12-05 00:40:58 +00:00
Leah Rowe 137b5434d7 remove logic for avoiding nonredistributable blobs
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

Leah Rowe e1bbdadc95 build/roms: remove seabios_grubfirst logic
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

Alper Nebi Yasak 6d6bd5eee0 build/roms: Rebuild cbutils module before starting coreboot build
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.

Alper Nebi Yasak 61ede99832 build/roms: Support using U-Boot as a coreboot payload
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.
