They rely on the NPCM7xx SoC device to do the heavy lifting. They are almost completely identical at the moment, apart from the SoC type, which currently only changes the reset contents of one register (GCR.MDLR), but they might grow apart a bit more as more functionality is added. Both machines can boot the Linux kernel into /bin/sh.
