Ok, I take it the 440EP really does have SDR and CPR devices with
which the EPx variants are compatible?

Should have an ibm,sdram-440epx entry as well, just in case of chip
specific bugs / workarounds.

What's the 440spe entry about?

Should have "ibm,ebc" too.

Again what's the ibm,emac-440spe about?
