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 41/65] nb/gm45: Fix Angel's DDR2 RCOMP fix on DDR3 boards

nb/intel/gm45: Make DDR2 raminit work
This patch was original applied, in lbmk, only on coreboot/dell,
separately from coreboot/default, which was wasteful because it
meant having an entire coreboot tree just for a single board. We
did this, because the DDR2 RCOMP fix happened to break DDR3 init
on other boards.
What *this* new patch does on top of Angel's patch, is make sure
that their changes only apply to DDR2, while DDR3 behaviour remains
unchanged. This means that the Dell Latitude E6400 can be supported
in the main coreboot tree, within lbmk.
Essentially, this patch restores the old behaviour, prior to applying
Angel's patch, only when DDR3 memory is used.
