From f52188b46ce60383b67aeea2bda7ec52d631c822 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/1] nb/x4x: define INTEL_GMA_DPLL_REF_FREQ
set it to 96MHz. fixes the following build error when
building for x4x boards e.g. gigabyte ga-g41m-es2l:
hw-gfx-gma-plls.adb:465:46: error: "INTEL_GMA_DPLL_REF_FREQ" not declared in "Config"
make: *** [Makefile:423: build/ramstage/libgfxinit/common/g45/hw-gfx-gma-plls.o] Error 1
this error was introduced when merging coreboot/dell
into coreboot/default in lbmk. nicholas chin's fix in lbmk
was as follows:
commit 8629873a6043067affc137be275b7aa69cb1f10c
Author: Nicholas Chin <nic.c3.14@gmail.com>
Date: Mon May 20 10:46:25 2024 -0600
Fix E6400 display issue with 1440 x 900 panel
this currently corresponds to the patch in lbmk,
as of 12 august 2024:
0042-mb-dell-e6400-Use-100-MHz-reference-clock-for-displa.patch
The assumption prior to Nicholas's fix was 96MHz, so set
it accordingly on x4x northbridge.
