NEW MAINBOARD: ThinkPad T480

2024-12-01T23:51:20+00:00

This uses the excellent deguard utility, written by
the excellent Mate Kukri.

A few bugs but it mostly works. Documentation to come
shortly, in lbwww.git.

Re-enable U-Boot x86 on real mainboards

2024-11-19T22:48:21+00:00

The previous stability issues were resolved, thanks to
the previous revision which added a fix courtesy Simon Glass.

This reverts commit eba73c778a85d1c6ad2f0de57c82a8775cdd1c17.

Disable U-Boot x86 except on Qemu

2024-11-19T16:22:14+00:00

It's really buggy on hardware. Disable for now.

I've contacted Simon Glass on IRC, asking about hardware.

Bump coreboot/next and merge coreboot/dell7

2024-11-06T22:32:45+00:00

coreboot/dell7 is now part of coreboot/next, which in turn
has been updated, to accomodate 3050 micro patchset 18:

https://review.coreboot.org/c/coreboot/+/82053/18

It incorporates my Verb/VBT patches, which are therefore
no longer included separately.

Mate has fixed the USB config; see diff for details.
The configuration of USB ports was wrong, before.

coreboot/dell3050micro: enable coffeelake CPUs

2024-10-31T02:38:01+00:00

pin mod needed (soldering) but according to mate, you
can use some coffeelake CPUs on these machines, despite
them being intel 7th gen. this includes 8-core chips.

this patch enables the software configuration in coreboot.

3050micro: Re-enable SeaGRUB

2024-10-27T19:32:36+00:00

Remove what is now unnecessary bloat, for ensuring that
GRUB is the primary payload; SeaGRUB is the only preference,
as per lbmk design.

The SeaBIOS hanging issue was fixed, so SeaGRUB is OK now.

3050micro: don't set static option table

2024-10-27T18:35:29+00:00

Again, I'm adapting the config to be as close to the
coreboot one as possible. I compiled directly from coreboot
earlier, and got SeaBIOS to work on my 3050.

I'm matching the setup as closely as possible. Once it works,
I can use that in a Libreboot release but then debug why the
old config wasn't working.

3050micro: Use alt century byte +legacy 8254 timer

2024-10-27T18:34:43+00:00

I'm eliminating as many differences as possible between lbmk's
setup, and the setup that is default when simply building from
the gerrit patch, directly in coreboot, by just picking the
mainboard; in this way, coreboot picks SeaBIOS as payload. I
already changed the SeaBIOS configs, in the previous patch.

Upon testing, this seems to have fixed the SeaBIOS hanging. I
need to have both of these options selected, or SeaBIOS hangs
just after it says "Press ESC" for the boot menu.

With this config change, SeaBIOS does not hang; instead, it shows
the list of devices as normal, and boots your machine.

Switch Dell 3050 Micro to newer coreboot revision

2024-10-27T01:15:24+00:00

Specifically, use the same revision that Mate used in patchset 15.

This will ensure that any issues are *not* caused by the coreboot
revision; this is being done, because the old coreboot revision was
from July, but patchset 15 from Mate is based on a September revision
of coreboot.

I've been eliminating as many variables as possible, trying to fix
SeaBIOS payload on this machine, because it hangs in Libreboot, but
not when building from gerrit directly, which means the coreboot
revision may be a factor (since I'm using his patches on an older
revision so upstream might have made some changes since then that
the port relies on).

For this, a new coreboot tree is used, called "dell7", referring to
the fact that Kabylake is Intel's 7th generation.
