[Skiboot] [PATCH RFC v2 00/12] opal-prd updates for p9

Hi all,

The following changes implement opal-prd functionality for P9. The core
change is the hostboot interface updates, and some base-level support
for the new callbacks.

Part of this series is the introduction of the opaque firmware <--> HBRT
channel, which means we should be able to avoid userspace (and kernel)
updates for future feature additions.

These patches are RFC only at this stage, and have ony had light
testing. Please let me know if you have any comments/changes.



 - Fixups from reviews from Vasant Hegde <hegdevasant at linux.vnet.ibm.com>
  - Check allocation return values
  - OCC chip argument parsing fixes
  - Extend occ chip specifier to process-error command
