Oh OK. In this case the GPMC is always within the 32-bit address space.
But considering that similar issue will be there for other code with
LPAE, how about add something generic to arch/arm/include/asm/io.h like:
#define PHYS_ADDR32(x) ((__force u32)(x))
#define PHYS_ADDR64(x) ((__force u64)(x))
Or maybe something like that already exists.

Tony
