[OpenBIOS] [PATCH 0/4] SPARC64: more *BSD fixups

[Mark Cave-Ayland]

This patchset follows on from my previous series and gets NetBSD/OpenBSD to
the same point as FreeBSD, i.e. the kernel starts to execute and we begin
enumerating hardware.

Getting these kernels to a point where they start to execute and enumerate 
hardware is a big milestone. Next step will be to fix up the extra properties
required by the *BSDs in the device tree.
