You may want to use the intelp2m tool afterwards to turn the output of inteltool into C code for the gpio.h file. I'm not sure from which comparison you want to draw those differences; I'd start with just dumping the vendor bios' GPIO configuration and then using that as a starting point in coreboot. > > 2. > > *Super I/O Delta:* If the physical Super I/O chip differs from > Gigabyte's ITE IT8718F, which primary configuration files (aside > from |Kconfig| and |devicetree.cb|) require updates? If you're in luck, you'd just adjust devicetree.cb with the correct superio chip (if already supported) and tune some settings. If coreboot does not support your chip already, you may need to write some code inside src/superio/. > > 3. > > *Native Raminit:* Are there any known routing or DIMM slot layout > edge cases that cause native |x4x| raminit to fail on non-reference > boards? Not that I know of. It will likely "just work" if the RAM SPDs are on the default addresses, and if not, you'll figure it out ;). (Worst-case is that raminit fails, but there should be no hardware damage, so you can just try it out.) Happy hacking!
