[U-Boot] Changing endianness of at91sam926x causes u-boot to crash

[dibacco at libero.it]

Hi all,

I have a board with at91sam9260 configured as little endian (via strap 
pin). The u-boot is working quite well.
On the board there is a chip whose 
driver was written for PowerPC that is big endian. Unfortunately the driver was

written in a bad way and it is difficult to fix endiannes dependencies. I 
thought to change the endianness of the processor
to big endian. I recompiled 
everything with a big endian compiler but the u-boot is crashing. Should I 
change something
on my hardware?
