2024-05-21Fix E6400 display reference clock patchesNicholas Chin
The ones I submitted before seem to have been outdated ones that don't actually build properly. Signed-off-by: Nicholas Chin <nic.c3.14@gmail.com>
2024-05-20Fix E6400 display issue with 1440 x 900 panelNicholas Chin
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.

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. Signed-off-by: Leah Rowe <leah@libreboot.org>

2023-11-05coreboot/dell: move e6400 to new tree, dellLeah Rowe
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.
