CPUs. And try to learn more on your on-board peripherals and devices.
Probably you can find some boards that have similar device
configuration, thus you can reuse some codes, esp. in case that you
should be not familiar with these devices.

If as SMP, you can run u-boot on one core and make the other core regardless for U-Boot, and make the other working when linux boots.
