-Subject: [PATCH 8/9] nb/intel/gm45: Make DDR2 raminit work
-
-List of changes:
- - Update some timing and ODT values
- - Patch RCOMP calibration to better match what MRC binaries do
- - Replay a hardcoded list of RCOMP codes after RcvEn
-
-This makes raminit work at DDR2-800 speeds and fixes S3 resume as well.
-Tested on Toshiba Satellite A300-1ME with two 2 GiB DDR2-800 SO-DIMMs.
