Subject: [PATCH 0/3 v5] Fixes for running a big-endian kernel on Cubieboard2

the following patches are what remains to be fixed in order to allow running a
big-endian kernel on the Cubieboard2.

The first patch fixes up endianness problems with DMA descriptors in
the stmmac driver preventing it from working correctly when runnning a
big-endian kernel.

The second patch adds the ability to enable diagnostic messages in the
sun4i-emac driver which were instrumental in finding the problem fixed
by patch number three: Endianness confusion caused by dual-purpose I/O
register usage in sun4i-emac.

All of these have been tested successfully on a Cubieboard2 DualCard.

Changes since v4:
- Rebased to current master
- Removed already applied patches to sunxi-mmc and sunxi-Kconfig

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
