Although 8MB seems to be the common size used. It can be very easy

You either have to provide a correct device tree for your board, or
use a boot loader / boot wrapper that fixes the flash base address and
size.
At the moment, U-Boot does not contain any code yet to do that
(patches welcome :-), and as far as I understand the cuImage wrapper
works just the other way round: it adjusts the mappings to the
settings in the device tree, which may or may not match the actual
hardware. This may work, but at least gives you a different flash
memory map in Linux than what you had before in U-Boot, so it's not
really nice either.
Hm... it seems the majority of MPC8272ADS boards seems to come indeed
with 8 MB NOR flash, so I wonder if the patch should actually go in?
Best regards,
Wolfgang Denk
Scott, any feedback if our boards have 8M or 32M flash modules?
