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
