[PATCH v4 05/17] arm: mach-dove: use IOMEM() for base address definitions
Thomas Petazzoni

Tue Sep 11 08:27:18 EDT 2012
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-dove 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.
