[Skiboot] [PATCHv2 00/13] NX 842 PowerNV kernel driver

[Dan Streetman]

These are the patches to add support for the NX-842 coproc on PowerNV.

Stewart, you can use this patch set to test on a p7+ system with
the two latest skiboot patches I sent, to add p7+ support, and
locate the 842 node under the main power-nx nodes.

This still contains direct xscom r/w, but I'll replace that with
opal calls, and send a new review patchset.

The only change in this patch set since v1 is to use the new
nx nodes under the main power-nx nodes in the device tree.

This also includes a nx-842 selftest module, but that's pretty rough
so you can ignore it, I don't plan on sending it upstream (at least not
in its current condition).  The generic comp_selftest is in better shape.
