allow multitree projects to define xgcc tree

2024-01-21T05:59:37+00:00

let them specific it, rather than falling back
to coreboot/default (can also be used for coreboot boards)

update/trees: further simplify crossgcc handling

2023-12-27T16:07:32+00:00

arch no longer needs to be set, on multi-tree projects,
and it has been renamed to xarch

the new behaviour is: if xarch is set, treat it as a
list of crossgcc targets and go through the list. set
the first one as the target, for what lbmk builds, but
build all of the defined crossgccc targets

crossgcc_ada is now xlang, and defines which languages
to build, rather than whether to build gcc-gnat

update/trees: simplified crossgcc handling

2023-12-21T14:18:51+00:00

only call crossgcc for coreboot and u-boot, but use
hostcc for everything else. simplify the checking of
which architecture to compile for. "arch" in target.cfg
files has been modified, to allow further simplification.

without this patch, the logic currently only *barely* avoids
using crossgcc on things like utils, and only works in practise
because, in practise, lbmk only works on x86_64 anyway.

the new logic, as per this patch, is simpler and more robust.

u-boot: gru: Do not persist EFI variables

2023-10-14T13:48:41+00:00

By default U-Boot stores EFI variables in a ubootefi.var file in
whatever EFI System Partition it finds, which would be a FAT filesystem.
I'm occasionally finding out while testing that my ESPs somehow end up
with a corrupted filesystem, and I'm suspecting it's this.

For now, disable storing EFI environment variables on disk so that
U-Boot doesn't try to manipulate the filesystem.

u-boot: gru: Enable more EFI commands

2023-10-14T13:48:41+00:00

Enable U-Boot commands to manipulate EFI environment storage, to
self-test EFI implementation, and to run a basic EFI test application.
These are so that we can test and debug EFI functionality easier.

u-boot: gru: Enable more bootstd features

2023-10-14T13:48:41+00:00

U-Boot upstream is switching to a new code framework for discovering and
booting OSes ("Standard Boot", or "bootstd"). Enable more features for
it, including commands we can use for introspection and debugging.

u-boot: gru: Do not reset on panic

2023-10-14T13:48:41+00:00

Normally U-Boot immediately resets the board on a panic. I had run into
"Synchronous Abort"s from shim and rEFInd, and having a traceback in
those cases can be useful. Hang instead of resetting, so the panic
reason stays on the screen.

u-boot: gru: Enable poweroff command

2023-10-14T13:48:41+00:00

We should be able to power the board off from U-Boot command line.
Enable the "poweroff" command for gru boards so we can.

u-boot: gru: Disable VIDEO_COPY

2023-10-14T13:48:41+00:00

U-Boot can keep a "copy" framebuffer to read from, for devices where
reading from hardware framebuffer is expensive. This needs the video
driver to support it. The Rockchip video driver doesn't need or support
it, so this option does nothing on gru boards. Disable it.

u-boot: Set EFI variable buffer size to upstream value

2023-10-14T13:48:41+00:00

U-Boot upstream used to have 16KB for EFI variables, and this was
causing problems with shim. Commit f0236acbc663 ("u-boot: Increase EFI
variable buffer size") fixed this by raising it to 32KB in our builds.
It has now been raised to 64K upstream, so raise it here as well.
