2024-05-21	fix building coreboot images on i686 hosts	Leah Rowe
	firstly, memtest86+ is currently not cross compiled and relies on 64-bit headers (x86_64 only). a 32-bit distro is unlikely to be able to build 64-bit binaries. secondly: vboot throws a build error due to -Werror when building on 32-bit hosts. we rely on vboot code to build cbfstool, so turn off -Werror on vboot that's all. 32-bit hosts are not recommended; it is assumed that you are building on an x86_64 host. work will go into the build system at a later date to make it more portable, by cross compiling everything, but this should fix 32-bit for now. there are some x60/t60 users who still want to build roms, so let's allow them that possibility.

2024-05-20	Fix E6400 display issue with 1440 x 900 panel	Nicholas 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.
