2013/2/21 Gabor Juhos juhosg@openwrt.org:
The purpose of the __raw* IO accessors is to provide IO access in native-endian order. However in the current MIPS implementation, the 16 and 32 bit variants of the __raw accessors are swapping the values on big-endian systems if the CONFIG_SWAP_IO_SPACE option is enabled.
The patch changes the IO accessor macros to fix this broken behaviour.

Note:
The change does not affect the existing MIPS targets because none of those are using CONFIG_SWAP_IO_SPACE. Compiling all MIPS targets results in the same binary image with and without the patch.
