We now define all virtual base address constants using IOMEM() so that those are naturally typed as void __iomem pointers, and we do the necessary adjustements in the mach-orion5x code. Note that we introduce a few temporary additional "unsigned long" casts when calling into plat-orion functions. Those are removed by followup patches converting plat-orion functions to void __iomem pointers as well.
