The core is there, but there is very little specific machine support. The one I use for testing is non-MMU ARM is the Atmel/AT91X40 (that is CONFIG_ARCH_AT91X40).

You can look at what I did with the AT91X40 for an example. Or look at the patches that Ithamar Adema sent to the ARM linux mailing list in the last few days for supporting the NXP LPC2K family as another example (they are also non-MMU parts).
