hmm....
include/asm-generic/io.h:#define ioread32be(addr)
__be32_to_cpu(__raw_readl(addr))
include/linux/byteorder/little_endian.h:#define __be32_to_cpu(x)
__swab32((__force __u32)(__be32)(x))
include/linux/byteorder/big_endian.h:#define __be32_to_cpu(x) ((__force
__u32)(__be32)(x))
i assume it should be available on all platforms. Or do i miss something?
