I'm using the driver with a 2.6.20 kernel, you have just to modify the 
low level I/O functions.  I don't know what is the effort for the 
mainline kernel. The blackfin/uclinux driver work as is with little 
endian architecture. If you have to use it with a big endian 
architecture I can send you a patch.
