Yes.

Yes this sounds reasonable. But later on in the patch serie we replace the
mgcoge2ne support with the support for mgcoge3ne which has a different SDRAM.
And therefore this common file would become obsolete. I try to rebase these
patches that the mgcoge3ne support is also part of this patch.

BTW: What would your proposal for a filename for a SDRAM specific header?
