Import sys/arch/arm32/{shark,ofw} bits of the Digital Network Appliance Reference Design NetBSD source code, obtained from the pages under http://www.research.digital.com/SRC/iag . Some of this code (badly) needs to be cleaned up, and as-is it doesn't compile. However, getting it in the tree is a start.
