and only where grub was already enabled; on boards
that did not enable grub, grub is still disabled
on desktops, it's possible that the user may insert
a graphics card. if their first payload was grub,
it won't work because lbmk doesn't configure coreboot
itself to execute vga roms at present
i found when testing t1650 (dell) that if a vgarom is
loaded from seabios (from a graphics card), the grub
payload still works; if booting in corebootfb mode,
text mode is still used when booting with the card
to decrease the probability of bricks with any given
set of users, make seabios the only payload that starts
first, but make grub available in the esc menu on seabios
it's possible to add a bootorder file and disable the
seabios menu, if you only want a grub payload accessible

they are fundamentally the same, in an lbmk context.
they are downloaded in the same way, and compiled in
the same way!
(Kconfig infrastructure, board-specific code, the way
submodules are used in git, etc)

coreboot revision:
d86260a134575b083f35103e1cd5c7c7ad883bce
from 2 August 2023
The patches were updated. HP 8300 USDT has now been merged upstream,
so that patch is no longer included in lbmk.
SD card fix for E6400 merged upstream, so now it's removed in lbmk.
The nvidia E6400 patch (devicetree.cb) has not yet merged upstream.
The ifdtool --nuke option has been rebased.
Patches as follow-ups to earlier patches removed; for example, patches
that set VRAM to 352MB on GM45 have been removed, and replaced with
patches that just set 256MB in the first place (this is more stable).
This was mostly a clean rebase, of all the patches. It went smooth.
I haven't updated cros/haswell yet; the 4.11_branch revision used
on fam15h will also remain, for now.
The coreboot configurations have been updated, for this new
revision of coreboot.

From now on, the following rules are available for all
mainboards, in resources/coreboot/boardname/board.cfg:
* blobs_required="n" or "y"
* microcode_required="n" or "y"
The blobs setting, if set to "n", simply renames filename.rom to
filename_noblobs.rom.
The microcode setting, if set to "n", copies the ROM (with or
without _noblobs) to filename_nomicrocode.rom (if blobs="n",
it would be filename_noblobs_nomicrocode.rom).
Where "nomicrocode" is set, ROMs with microcode will still be
provided by lbmk and in relesase, but ROMs will also be provided
alongside it that lacks any microcode updates.
If the *original* ROM already lacks microcode updates, then the
original ROM will be *renamed* to include "nomicrocode" in the name.
This is done on images for ARM platforms, for instance, where
microcode is never used whatsoever.
Example filenames now generated:
seabios_e6400_4mb_libgfxinit_corebootfb_noblobs_nomicrocode.rom
seabios_e6400_4mb_libgfxinit_corebootfb_noblobs.rom
seabios_withgrub_hp8300usdt_16mb_libgfxinit_corebootfb_colemak_nomicrocode.rom
seabios_withgrub_hp8300usdt_16mb_libgfxinit_corebootfb_colemak.rom
uboot_payload_gru_kevin_libgfxinit_corebootfb_noblobs_nomicrocode.rom
A vocal minority of people were not happy with some of the changes
made in Libreboot last year, including on existing supported
hardware from before those changes were made. I did this before the
last release, out of respect:
https://libreboot.org/news/gm45microcode.html
(re-add mitigations for no-microcode setup on GM45)
This new change is done as an further, extended courtesy. Tested
and works fine. (testing using cbfstool-print)
Actual Libreboot policy about binary blobs is nuanced. See:
https://libreboot.org/news/policy.html (reduction policy) and:
https://libreboot.org/freedom-status.html (implementation)
Well, the status page talks about descriptor vs non-descriptor
on Intel platforms, and where me_cleaner is used (on platforms
that need Intel ME firmware), it regards the descriptored setups
to be blob-free if coreboot does not require binary blobs.
In this paradigm, microcode updates are not considered to be
binary blobs, because they aren't technically software, they're
more like config files that just turn certain features on or off
within the CPU.
However, for lbmk purposes, "noblobs" means that, after the ROM
is fully ready to flash on the chip, there will be no blobs in
it (except microcode). So for example, an X200 that does not
require ME firmware is considered blob-free under this paradigm,
even though Libreboot policy regards X230 as equally libre when
me_cleaner is used; in this setup, ROMs will not contain "blobfree"
in the filename, for X230 (as one example).

osboot is now part of libreboot, and will soon shut down.
libreboot now conforms to osboot policy.

tianocore is a liability for the libreboot project. it's a bloated mess, and
unreliable, broken on many boards, and basically impossible to audit.
i don't trust tianocore, so i'm removing it.

you must de-solder the default chip and install the new one.
winbond w25q128fvsig is a nice choice of 16MB (128Mbit) IC
