It would be a lot easier if you modified the application to work on big-endian
and little-endian. Just look through the code in places where the endian
matters, and add cpu_to_be32() and be32_to_cpu() (or similar functions).
The only time this will be real problem is with DMA, since on 83xx you cannot
modify the data during a DMA transfer.
