[coreboot] [PATCH 0/4] Geode GX2 auto DRAM detect patch V2

[Nils]

This patch series splits up the Geode GX2 auto DRAM detect patch into 4 
patches as requested.
It should be easy to review now.

The patches are Abuild and boot tested on my Wyse S50 .
They should be applied in this order.

Thanks, Nils.
