I'm looking for a no-strings-attached .h file to include in PowerPC
(GNU as) assembler code. You know with things like:

#define r0      0

(and SPR register numbers etc.). Multiple CPU support would be nice.
Looks like various linux code bases have a ppc_asm.h, but it's GPLed.
Seems like IBM, Freescale, etc. would have something, but no luck. At
this rate I'll just type it myself...
