[PATCH V7 0/3] powernv : Add support for OPAL-OCC command/response interface

[Shilpasri G Bhat]

In P9, OCC (On-Chip-Controller) supports shared memory based
commad-response interface. Within the shared memory there is an OPAL
command buffer and OCC response buffer that can be used to send
inband commands to OCC. The following commands are supported:

1) Set system powercap
2) Set CPU-GPU power shifting ratio
3) Clear min/max for OCC sensor groups

The skiboot patch for this interface is posted here:
