nb/intel/gm45: Wedge DDR2 SPD support in
Add initial support for DDR2. This also changes GM45 raminit to
internally work in units of 1/256 ns for both DDR2 and DDR3 instead of
the 1/8 ns MTB assumed for DDR3, which simplifies the handling of time
values. DDR3 time values are thus scaled by a factor of 32 accordingly.
TODO:
- DDR2 JEDEC init
- Memory IO init
- Register programming
TEST: DDR2 systems boot (with the rest of the patch train)
- Tested on a Dell Latitude E6400
- Tested on a Compal JHL90
TEST: Ensure DDR3 systems still boot
- Tested on a Thinkpad X200
