Leah Rowe 99a88ebfa2 Update dell 3050 patch to patch 15 (pwm fix)
Use patchset 15 instead of 14:
config/coreboot/default/patches/0061-WIP-OptiPlex-3050-Micro-port.patch

Rebase the verb patch; patchset 15 modified the Makefile:
config/coreboot/default/patches/0064-dell-optiplex_3050-add-hda_verb.c.patch

We were using patchset 14 for the 3050 micro:
https://review.coreboot.org/c/coreboot/+/82053/14

Now we use patchset 15:
https://review.coreboot.org/c/coreboot/+/82053/15

Without this patch, the fans are always on a low setting, on
the Dell OptiPlex 3050 Micro, even under stress conditions. With
this patch, the fans change speed according to CPU temperature.

I had to rebase my verb patch, because Mate modified the Makefile
to add his sch5555 handler, on the same line where I add hda_verb.

Mate tells me he will merge my verb and vbt patches into a further
patchset later on. For now, I've simply rebased these patches on
top of Mate's newer work; I've told him he can use them in his port.

I'm probably going to now issue a new revision ROM image for
Libreboot 20241008, so that users can get this fix sooner.

Subject: [PATCH 11/65] lenovo/x230: set me_state=Disabled in cmos.default
I only recently found out about this. It's possible to use me_cleaner to
do the same thing, but some people might just flash coreboot and not do
anything with the ME region
With this change, the ME is set to disabled. It's my understanding that this
will accomplish more or less the same thing as me_cleaner, without actually
using that. Of course, I still recommend using me_cleaner
I saw this when I audited coreboot's git history, and saw this:
