[Skiboot] [PATCH v5 0/4] Add Secure Variable Support

[Eric Richter]

This version of the set is focused on revising the device tree nodes and
properties to be exposed for secure variables. The set has been trimmed
to only contain the core code needed for base secure variable support,
and the storage/backend drivers have been removed for sake of brevity.

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
