[coreboot] Errors in Memtest86 with 4 or 8GB memory

[Krzysztof Pierwieniecki]

I have a problem on Intel DQ77KB board. I have two the same boards and 
on every board Memtest86 reports a problem at 2990.8MB. That problem 
occur only if I use 4 or 8GB memory. With 2GB memory everything is OK.

What may be causing errors in Test2 "Address test, own address, 
Parallel"  in Memtest86?
