Thanks. Nice work. But I see some problems on my PPC4xx system:

a) Crashes upon flashing 16MBytes

=> cp.b 100000 fe000000 1000000
Copy to Flash

Bad trap at PC: 20202020, SR: 29000, vector=1400
NIP: 20202020 XER: 0000005F LR: 20202020 REGS: 0ff15950 TRAP: 1400 DEAR:

MSR: 00029000 EE: 1 PR: 0 FP: 0 ME: 1 IR/DR: 00

b) Strange output upon "saveenv" with redundant env sectors:

=> saveenv
Saving Environment to Flash...
. done
Un-Protected 1 sectors
. done
Un-Protected 1 sectors
Erasing Flash...
. done
Erased 1 sectors
Writing to Flash... |

done
.......|
. done
Protected 1 sectors
. done
Protected 1 sectors

It seems we have to restrict the output length somehow for this 16MByte 
problem. Or perhaps use a fixed length for all sizes.

Best regards,
Stefan
