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
previously, it was always initialised, but now it's only
initialised if '?' is used on a mac address character in
command `setmac`
this is done by simply moving mac address character
randomisation to a separate function
If one of the checksums was valid, but the other was not,
errno would be set to E_CANCELED, but then the buffer would
be modified anyway; this is acceptable behaviour, and errno
would later be reset writing the GBE file, which is done
only on the condition that the buffer was modified, but
it's also a good idea to reset it here just in case.
This is not a bugfix, and no behavioural changes will be
observed by the user, but this may *prevent* a bug in the
future, so let's pre-fix that bug now.
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.
in any C program, main() should not contain detailed logic.
ideally, the main() function should only be a skeleton, showing
the overall logic flow of the program. split writing gbe files
into a separate function, to satisfy this criteria.
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
