If you aren't using any driver existing driver but only newly written dedicated for that SOC you could use raw_read/raw_writeX() instead. These type of functions are always using native endianess. > What makes SWAP_IO_SPACE generic then? :) als long as hardware presents memory used with readX/writeX is seen as little endian independant from CPU endianess it's generic.
