The other important point is that these cores are ARMv4, and at
the moment target-arm/ kind of assumes ARMv5. I believe there have
been patches proposed before to add ARMv4 support, eg
 http://patchwork.ozlabs.org/patch/36841/

Rough list of things that need to be done:
 * make sure we don't ever switch to thumb mode (and for v4T
   make sure we switch to thumb mode only for BX)
 * undef on instructions that are new in v5
 * support base-updated abort model (not actually needed for
   StrongARM)

Have I missed anything?
