Hi, I have ported three boards with the cougarpoint H61 PCH, so I hope I can help you out.

While it is not a blocker, it means stuff like GPIO configuration will need to be copied from vendor firmware (misconfigurations could result in short-circuits).

Unfortunately, native RAM init does not have support for ECC memory initialization, at least last time I checked. I do not know which superio your board has, but you would want to make sure it is supported (or just add support for it) because serial ports on the SuperIO can be used to get coreboot log output.

There are several sandybridge and ivybridge Thinkpads in the coreboot tree. The mainboard-specific documentation has pages for several sanybridge and ivybridge mainboards. I am sure of that since I added documentation for two of these boards myself. I think there are also some pages about the memory controller inside these processors. Inside the tree, take a look at src/northbridge/intel/sandybridge and src/southbridge/intel/bd82x6x. Even though the names refer to sandybridge and cougarpoint, the code also supports ivybridge and pantherpoint. This lack of accessible documentation makes it difficult to find good >> porting candidates for hardware of *any* generation. Are all ivy bridge >> CPUs supported?

FSP is not used on sandybridge nor ivybridge coreboot. If you ask me, *anything* is a potential porting candidate if you feel like investing the time.
