In commit bf5f0019046d596d613caf74722ba4994e153899, Heiko fixed this for 32-bit PowerPC; my patch now generalizes upon that. The device is now recognized correctly for both litte-endian and big-endian sh7785lcr, but I have not tested this any further, as the board is situated in a remote data center.
