Hmm, I tried with these setting (and many others) to make the flash on my 
board work again.
But the physmap_of.c driver always fails. It tries to request the region 
0xfe000000 to 0x00000000 (my flash is 32MiB in size at 0xfe00000 to 
0xffffffff) and fails badly. What are the correct settings in the OFTree to 
make the physmap_of.c driver work?

Regards,
Juergen
