[coreboot] v3 starter project

[Carl-Daniel Hailfinger]

Hi,

some of you are looking for an easy way to get involved with coreboot v3.
Maybe the easiest task would be a refactoring of
northbridge/amd/geodelx/raminit.c. That code has lots of duplications
all over the map due to the fact the code was originally written for
ROMCC efficiency. You may save more than 30% code size and probably
quite a bit of execution time by killing duplicates and moving the
"invalid SPD" checks to some generic function. There's simply no need to
check and calculate the same stuff over and over again.

Regards,
Carl-Daniel
