Subject[PATCH 2/2] ARM: at91: Use proper __iomem annotations
Date
From: Arnd Bergmann <arnd@arndb.de>

MMIO addresses should be of type 'void __iomem *', not integer,
in order to make the build-time type system of the kernel work.

This changes some of the locations in the at91 platform that
I noticed, but there may be more, since I have not yet built
every configuration.
