Hi,
in v2 we enable full ROM decoding before initram. For VIA C7 and Intel Core 2 Duo, that means the CAR area is inside the mapped ROM contents.
That observation is wrong for the intel core case. CAR lives 1MiB below the rom there. So no problems arise.
Core 2 Duo CAR lives at 0xFFEF0000 with a size of 32 kiB in v3. Core 2 Duo CAR lives at 0xFFDF8000 with a size of 32 kiB in v2 for the Kontron board.
My observation is correct for any ROM larger than 1 MiB (to be exact, 1024+64 kiB) in v3 and for any ROM larger than 2 MiB (2048+32 kiB) in v2.
How variable is the location where we can have CAR in the Core 2 Duo? Is anything in the top 16 MiB allowed?
