I'm without r600 hardware this week, but personally I think I'd be
happier with a helper function for the endian swap, instead of
sprinkling ifdefs all over the source code.

E.g., something along these lines:

static inline unsigned r600_endian_swap(unsigned size)
{
#ifdef PIPE_ARCH_BIG_ENDIAN
    switch (size)
    {
        case 16:
            return ENDIAN_8IN16;
        case 32:
            return ENDIAN_8IN32;
        case 64:
            return ENDIAN_8IN64;
        default:
            return ENDIAN_NONE;
    }
#else
    return ENDIAN_NONE;
#endif
}
