 Coreboot times out with the following on Gigabyte GA-MA785GMT-UD2H (rev.
 1.1) + AMD Phenom XII 955 (HDZ955FBGIBOX) processor:


 {{{
 F3xDC[PstateMaxVal] is zero. Northbridge voltage setting will fail.
 fixPsNbVidBeforeWR in fidvid.c needs fixing. See
 *** Time out waiting for P-state 1. Current P-state 0 P-state current
 limit MSRC001_0061=00
 }}}

 The same Coreboot rom will boot with a AMD Athlon II X2 245 processor.
 Debug logs attached; it's an important fix and any patches welcome.
