The only purpose of legacy flash boards is to be flashed over vendor
firmware using an exploit, to then flash non-maximized Heads firmware.
They are never upgraded to another legacy flash build, and they move
the coreboot ROM from the build directory, so don't build an update
package for those boards.

Enabling DEBUG/TRACE options from board config vs from configuration menu is different.
When enabled in board config, /etc/config is from ROM, and sourced early and make TRACE/DEBUG calls appear early.
If added through configuration menu, those are /etc/config.user overrides extracted from CBFS and then sourced after combine_configs call
If for whatever reason early DEBUG is needed on a platform, enabling in board config is needed.
For runtime debugging, enabling Debug output from configuration menu is enough
Add Librem 11 board.
Librem 11 uses coreboot graphics init, which is done with FSP GOP.
Set a custom keymap for the volume/power keys. Configure the volume
keys as up/down arrows (for navigation in fbwhiptail, and for shell
history in the Linux console). Configure the power key as Enter.

Update all Librems except L1UM (but including L1UM v2) to Linux 6.1.8.
Use coreboot native graphics init. Raise maximum framebuffer size for
laptops to 3840x2160 (desktops default to this, but laptops default
to a lower value). Remove DRM modules from Linux 6.1.8 and add EFIFB.
Remove Heads kernel command line options relating to IOMMU and i915,
which are no longer needed. Remove OS kernel options relating to
IOMMU.
For Librem 13/15/14/Mini, this fixes issues booting with 4K displays
attached, which were resulting in crashes due to the framebuffer memory
not being reserved properly. memtest86+ now passes with a 4K display
attached.
For Librem L1UM v2, framebuffer boot now works.
Librem L1UM remains on Linux 5.10 with Heads kernel graphic init
(framebuffer boot still does not work). coreboot 4.11 has native
graphics init for Aspeed, but only in text mode. Backporting the
linear framebuffer support appears to be possible - the patch applied
cleanly - but it did not work initially and will need more
investigation.

Enable the coreboot CMOS option table, which initializes CMOS if the
checksum is not valid.
There is now a checksum in the CMOS layout since 4.21, update it when
updating the Mini v1/v2 EC power-on setting.
coreboot 4.21 will reset the CMOS settings during the first boot, since
there was no checksum in prior releases. Heads will restore the
automatic power-on setting during init based on config.user.

Rationale:
cpio -t alone cannot extract initrd past early cpio (microcode) in most packed initrd.
unpack_initramfs.sh already under master comes to the rescue, but its usage up to today was limited to pass firmware blobs to final OS under boards/librem_mini_v2
Debian OSes (and probably others) need to have cryptroot/crypttab overriden directly, otherwise generic generation of crypttab is not enough.
Extracting crypttab and overriding directly what is desired by final OS and exposed into /boot/initrd is the way to go otherwise hacking on top of hacks.
This brings default packed modules under Heads to 5 modules, which needs to be deactivate in board configs if undesired:
user@heads-tests-deb12:~/heads$ grep -Rn "?= y" modules/ | grep -v MUSL
modules/zlib:1:CONFIG_ZLIB ?= y
modules/zstd:3:CONFIG_ZSTD ?= y
modules/exfatprogs:2:CONFIG_EXFATPROGS ?= y
modules/busybox:2:CONFIG_BUSYBOX ?= y
modules/e2fsprogs:2:CONFIG_E2FSPROGS ?= y
Include kbd so the console font can be enlarged based on the display
resolution.
Don't force 1080p on the eDP output in Heads.

These boards get purism-blobs as a submodule of the purism coreboot
fork. modules/coreboot used to skip the purism-blobs dependency for
this fork, but the module is not needed at all for these boards.
librem_l1um keeps CONFIG_PURISM_BLOBS=y since it is built from patched
coreboot 4.11.

For iterating, enabling these in the board config is easiest. It's
also possible to manually inject config.user ahead of time, or enable
at runtime without flashing, but the normal enable/flash/reboot path
does not work in qemu since it is unable to flash.
