help with MPC8272ADS board

[Landau, Bracha]

I've upgraded to the latest kernel (2.6.29), and after updating the configuration the cuImage did boot.
What's the difference between the address for the early debug console for cuImage and uImage + blob?

2.6.24 is nowhere near the latest version of Linux.  If you specifically want to use a Denx kernel, you're better off at eldk at denx.de -- though I'd be surprised if that's the latest they offer, either.

I'd rather change the device tree, instead.

Upgrade to the latest kernel, and if it still doesn't work try enabling the early debug console (note that the default address is currently for cuImage).
