This tries to clear up the confusion between integers and iomem pointers in the marvell pxa platform. MMIO addresses are supposed to be __iomem* values, in order to let the Linux type checking work correctly. This patch moves the cast to __iomem as far back as possible, to the place where the MMIO virtual address windows are defined.
