coreboot/dell: merge into coreboot/default

2024-08-09T19:55:42+00:00

The libgfxinit patch and other patches e.g. DDR2 fix, are
now provided in coreboot/default. The Latitude E6400 is now
using the newer coreboot revision from late July 2024.

Some other configs had to change because of this, relating to
the new way that Nicholas handles timing on LVDS displays
with the E6400 port; a default 96MHz clock is still used for
pixel reference clock, overridden with a value of 100MHz on
other GM45 machines, where 96MHz was previously hardcoded.

Fix E6400 display reference clock patches

The ones I submitted before seem to have been outdated ones
that don't actually build properly.

Fix E6400 display issue with 1440 x 900 panel

2024-05-20T16:46:25+00:00

The E6400 uses a 100 MHz reference clock on DPLL_REF_SSCLK, whereas
libgfxinit assumed that the reference was always 96 MHz. The frequency
difference caused by a 100 MHz reference with PLL config values
calculated assuming a 96 MHz reference were not significant enough to
cause noticable issues with the more common 1280 x 800 panels, but are
enough to matter for the 1440 x 900 panels which use a higher pixel
clock. This only affected the pre-OS graphics environment provided by
libgfxinit, as Linux drivers would determine the reference clock
frequency based on data in the VBT.

Fix this by making the reference clock frequency in libgfxinit
configurable for GM45 based on a new coreboot Kconfig, which is set to
100 MHz for the E6400.

update coreboot/dell to same rev as default

2024-01-25T16:09:19+00:00

re-use the same patches, and drop the same patches.

this tree uses hell's special ddr2 fix, which we apply
for the dell latitude e6400.

coreboot/dell: move e6400 to new tree, dell

2023-11-05T12:23:42+00:00

the ddr2 fix broke *ddr3* on gm45 thinkpads in
testing, depending on memory modules. this was
established by removing patches, re-doing
configs etc, on a user's X200 (testing gentoo
and freebsd). the X200 kept randomly rebooting
or having random glitches.

the configs themselves (gm45 thinkpads) will
also be re-done, because i found minor issues
unrelated, but this patch moves dell e6400 to
its own tree. the ddr2 fix is no longer present
in coreboot/default, only coreboot/dell.

i noticed minor differences in gm45 thinkpad
configs, when re-doing the configs, versus
what are currently in lbmk master; for instance,
vbt was not enabled anymore, on thinkpad x200.
modifications to these will be done separately.
