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?

Juergen
