These values (and the gmpc_m_nand ones) are platform specific, right? It
would be nicer to have them in the board file than here, similar to how
I did for the ddr settings some time ago.

So now you cannot E.G. have a single binary working on both the nand
flash of the evm and beaglebone? That's not really nice.
