Hmm, I tried with these setting (and many others) to make the flash on my=20
board work again.
But the physmap_of.c driver always fails. It tries to request the region=20
0xfe000000 to 0x00000000 (my flash is 32MiB in size at 0xfe00000 to=20
0xffffffff) and fails badly. What are the correct settings in the OFTree to=
=20
make the physmap_of.c driver work?
