They should both be specified, and either in the firmware or in the
platform code you need to set CMXSMR.

If you remove the chosen node, you won't get any output from the
bootwrapper, but it shouldn't crash.

The ep8248e bootwrapper platform is for planetcore (as that's what the
board ships with). If you're using u-boot, it's the cuboot-pq2 platform
that you want to use. Just make zImage and boot the cuImage.pq2 file.
