it's board specific. I added a new patch for s3c440 gpio driver. Now in the
board file we have no more magic bloat.

About this point, I ported it from the old version uboot as well. It may need
some investigation, but I remember it was a big problem with this board. In the
case of a NAND boot, we don't have access to NOR because the SteppingStone
(SRAM) is mapped at the same range.

  Add GPIO Driver and IOMUX definition for S3C2440
  Add support for MINI2440 (s3c2440).
