branches:  trunk

description:
remove pyro_xir().  we don't have the MD support for it (yet?).
clean up some debug code.  clean up the DPRINTF() code, and expand
the interrupt mapping debug code to match schizo and psycho.
set IOMMU_TSBSIZE_IN_PTSB, and if oberon, IOMMU_FLUSH_CACHE.
disable the STC explicitly.
