Leah Rowe 66d084e7f7 grub.cfg: scan luks *inside lvm*
the user might have boot their kernel inside luks
inside lvm for some dumb reason

it's theoretically possible that the user would be
so silly indeed

Leah Rowe 5a3b0dab96 grub.cfg: Scan *every* LVM device
We were scanning a hardcoded set up LVM volumes, so in practise,
LVM boot didn't really work. We did this because scanning for
asterisk is slow on some machines. However, since LVM is the last
one, and since most users don't boot directly from LVM, it wasn't
that much of an issue in practise.

Leah Rowe eb14a176bc Only boot 32-bit u-boot from grub, 64 from seabios
For some reason, 32-bit U-Boot only works when executed from
GRUB, but not SeaBIOS; 64-bit U-Boot only works from SeaBIOS!

This will have to be investigated. Standalone U-Boot, where
U-Boot is the primary payload, has not yet been tested in
Libreboot, and will not be provided for some time due to
stability concerns. More testing is needed!

Leah Rowe 709bbebdcf grub.cfg: mark U-Boot as experimental in the menu
it's important that we maintain realistic expectations.
x86 u-boot is not yet fully stable, so mark it as such.

Leah Rowe 747b6514ea Add U-Boot x86_64 payload
Currently seems to stall when booted from the GRUB
payload, but works when booted from the SeaBIOS menu.

I also tested it as a standalone payload and it seems
to boot. Will test on hardware next, and start adding
it to more mainboards.

Leah Rowe c0017c7357 Experimental U-Boot payload (32-bit dtb, U-Boot)
NOTE: Support added for xarch target x86_64-elf,
but U-Boot failed to build with this error:

OBJCOPY lib/efi_loader/helloworld.efi
x86_64-elf-objcopy: lib/efi_loader/helloworld_efi.so: invalid bfd target
make[2]: *** [scripts/Makefile.lib:476: lib/efi_loader/helloworld.efi] Error 1

Since I'm building U-Boot for x86_64 *on* an x86-64
host, and since that is currently the recommended type
of machine to use for lbmk development, and since the
other x86 payloads currently don't cross compile anyway,
this is an acceptable compromise for now. This is because
at present, I'm not making U-Boot the primary payload on x86,
instead preferring to chain it from GRUB and SeaBIOS.

The target.cfg file for x86 u-boot shows xarch/xtree commented.
Uncomment these to compile on crossgcc instead of hostcc.

I mention 64-bit because I initially did this first, but decided
to do 32-bit first. I'll work on the 64-bit one next (SPL).

It's only enabled in QEMU for now.

Leah Rowe 893e88bc81 roms: don't insert timeout.cfg
this is bloat, because it's something the user can already
do at runtime configuration anyway.

set it to a reasonable default of 8 seconds instead of 5,
and don't honour the timeout variable in target.cfg.

this will be documented in the next release.

Leah Rowe 340eea0b1c grub: insert background in memdisk instead
the background is only a few kb. the whole rationale
before was to limit the space used in memdisk, but this
decision was made when the background was much bigger;
it has since been optimised greatly, and the grub modules
were heavily reduce, so it should be safe.

grub's memdisk breaks when you add too much data to it.
as part of simplifying the rest of lbmk, this change removes
some more bloat from the rest of lbmk. handling this in the
memdisk is much simpler than handling it with cbfstool.

Leah Rowe 0b37653ab9 grub: only enable nvme if needed on a board
remove nvme support from the "default" grub tree

now there are three trees:

* default: no xhci or nvme patches
* nvme: contains nvme support
* xhci: contains xhci and nvme support

this is in case a bug like lbmk issue #216 ever occurs
again, as referenced before during lbmk audit 5

there is no indication that the nvme patch causes any
issues, but after previous experience i want to be sure
