Carl-Daniel Hailfinger ea0fbc9514 Changed RAM speed calculation to fix RAM modules getting rejected only 
due to integer rounding errors. Previously, the formula was:
        speed = 2 * (10000/spd_value)
For spd_value=60 this means speed = 2 * 166 = 332, which is less than
333 and coreboot died saying RAM was incompatible. The new formula is:
        speed = 20000 / spd_value
For spd_value=60, speed=333, which is fine.

k8 This is a small HT fixup until HT links get figured out better. 2009-01-08 16:22:39 +00:00
