The SuperH architecture allows to be run in either little or big endian mode. Some SuperH SoCs get the little vs. big endian decision through mode pins sampled at reset, so if big endian has been choosen by HW designers, it cannot be easily changed. Therefore, it makes sense to allow building U-Boot for SuperH in big endian mode. To allow this, the only change needed is to adjust the OUTPUT_FORMAT() in the linker script.
