commit 15e268ee435d7d6f8d76997336efb38c4732042e Author: Marc Jones marc.jones@se-eng.com Date: Tue Feb 21 17:06:40 2012 -0700
Fix ECC disable option for AMD Fam10 DDR2 and DDR3.
The logic was backwards on the ECC enable/disable option. Also added better debug output when the debug RAM init feature is enabled.
