[Skiboot] [RFC PATCH v4 00/16] Ultravisor support in skiboot

[Ryan Grimm]

Oliver,

I replied to the thread from last month and fixed up a lot of stuff based on
your comments.

We had a question - can we dual license this stuff?

TODOs

1) Fix up ucall to follow hcall convention and provide functions for 4 args and
9 args

2) log XSCOM errors in skiboot

3) local_free unit test

4) replace define for uv_image_size by probing or device tree

5) reserve the region used by uv for mambo and bml

Thanks,
Ryan
