I am upgrading from 1.1.3, that shipped on the board.

I am pretty confused by your notes as they relate to my image.  For me,
I am flashing at fff00000.  This is sufficient to brick the board :-D.
It seemed like your notes were reflecting a change in the boot address
between versions?  I tried to use the addresses you mention and 1)
fe000000 tells me it is not erased, even after I erase it (?) and 2)
fe700000 seems to have no effect. I thought those were the u-boot
locations for the mpc8349ITX (?).

Just to be clear, I am not even at the point of booting the kernel, just
trying to get to the u-boot prompt of a new u-boot.

I really appreciate the help!  Unfortunately, I am just more confused at
the moment.
	Thank you,
		Michael
