---------^^^^^

That's the problem. The board we got from AMCC for the port  and  for
testing  all had 64 MB flash, and there was no information that other
configurations are available too. The MTD mapping driver  ist  a  bit
braindead at the moment and assumes 64 MB. This fails on your board.

The quick and dirty fix is to edit "drivers/mtd/maps/yosemite.c" and
replace the lines:

    ...
     31
     32 #define WINDOW_ADDR 0xfc000000
     33 #define WINDOW_SIZE 0x04000000
     34
    ...

with:

	#define WINDOW_ADDR 0xFE000000
	#define WINDOW_SIZE 0x02000000

We will implement a better fix (automatically adjust values according
to the values pased by the boot loader) later today / early tomorrow.

Sorry for the inconvenience.

Best regards,

Wolfgang Denk
