Hello, the following patches allow to run a big-endian kernel on the Cubieboard2. The first two patches fix up endianness problems with DMA descriptors in the sunxi-mmc and stmmac drivers preventing them from working correctly when runnning a big-endian kernel. The third patch adds the ability to enable diagnostic messages in the sun4i-emac driver which were instrumental in finding the problem fixed by patch number four: Endianness confusion caused by dual-purpose I/O register usage in sun4i-emac. The final patch enables the big-endian kernel configuration option for sun7i devices in order to be able to compile a big-endian kernel for the Cubieboard2. All of these have been tested successfull on a Cubieboard2 DualCard. Changes since v3: - Rebased sunxi-mmc patch against Ulf's mmc.git/next - Changed Kconfig change to enable big-endian support only for sun7i devices Changes since v2: - Fixed typo in stmmac patch causing a build failure - Added sun4i-emac patches Changes since v1: - Fixed checkpatch niggles - Added respective Cc:s Regards, Michael Signed-off-by: Michael Weiser <redacted> Cc: Maxime Ripard <redacted>
