[Skiboot] [PATCH v6 0/5] Add Secure Variable Support

[Eric Richter]

This version of the set further revises the device tree nodes and
properties for secure variables. As before, this is a trimmed set to
only include the base requirements.

Changes in V6:
 - moved os-secureboot-enforcing to ibm,secureboot
 - removed backend node from secvar node
 - set secvar compatible based on the backend in use
 - updated documentation for the above
 - added a generic compatible to ibm,secureboot

Changes in V5:
 - rewrote the device tree bindings document
 - removed storage child of secvar node
 - adjusted the code to use new device tree layout
 - removed unused, or old code that is no longer needed

Eric Richter (4):
  doc: add opal secure variable documentation
  libstb/secvar: add secure variable internal abstraction
  libstb/secvar: add secvar api implementation
  secvar/test: add rudimentary secvar API unit testing

  hdata: Add a generic compatible to ibm,secureboot
