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
buggy, buggy, buggy, buggy, buggy, buggy, buggy
full of bugs, these boards never worked properly. i got ripped
off with these.
now i'm ripping off the band aid
use dasharo if you want d16 stuff. i'm done with it.
python2 is eol and the only thing that needed it was build scripts
inside tianocore, back in osbmk days when tianocore was supported
in the (osboot) build system. nothing else requires it, so chuck it
This adds U-Boot configuration for the Samsung Chromebook 2 13", also
known as "peach-pi" in the U-Boot upstream defconfigs. It uses the
shared tree for the "peach" baseboard. The config is almost the same as
upstream defconfig, but with REMAKE_ELF and POSITION_INDEPENDENT
enabled.
Untested since I don't have the peach pi chromebook. Note the there
doesn't seem to be any coreboot support for this chromebook.

This adds coreboot configuration for the Samsung Chromebook 2 11", which
is based on the "google/peach_pit" mainboard in upstream coreboot. Also
adds a shared "peach" board directory to share with others having the
same baseboard.
The config is based on the following defconfig:
CONFIG_VENDOR_GOOGLE=y
CONFIG_CBFS_SIZE=0x00400000
CONFIG_UART_FOR_CONSOLE=3
CONFIG_BOARD_GOOGLE_PEACH_PIT=y
CONFIG_CONSOLE_CBMEM_BUFFER_SIZE=0x20000
CONFIG_UART_PCI_ADDR=0x0

Untested since I don't have the peach pit chromebook. This also fails
without a non-free 3rdparty/blobs/cpu/samsung/exynos5420/bl1.bin blob.
