Yep, this is a P2020.

I'll check the Freescale documentation. Hopefully it provides an example
of how to configure the On-Chip ROM to use L2SRAM instead of DDR.

I'll try and find a U-Boot port that configures DDR via SPD. I'm sure
there are plenty, however any hints are welcome. :)

Thanks for the input,
