I'm not aware of any work in this area, although you're wellcome to give
it a try.

The HAL CPUs are quite different from UltraSPARCs.  I expect the MMUs to
be significantly different, so pmap.c and lots of locore.s would need to
be rewritten.  And they probably don't support any of the VIS extensions
like block load/store.

The first step on such a project is to get the documentation on the CPU
and bus controllers.  Good luck.
