LS1043 (ARM, Little Endian) support is still work in progress.  The patches for that are being tested now but are based on the SDK version of the driver and will need to be massaged in order to get them applied here.  Our plan of record is to add upstream support for this at a later time.

Yeah - I recall fixing this when doing the ARM port but I guess I didn't make the same change in this version.  I will address this in the next version.
