#     integrity/powerpc: Support loading keys from PLPKS
#     
#     Add support for loading keys from the PLPKS on pseries machines, with the
#     "ibm,plpks-sb-v1" format.
#     
#     The object format is expected to be the same, so there shouldn't be any
#     functional differences between objects retrieved on powernv or pseries.
#     
#     Unlike on powernv, on pseries the format string isn't contained in the
#     device tree. Use secvar_ops->format() to fetch the format string in a
#     generic manner, rather than searching the device tree ourselves.
#     
#     (The current code searches the device tree for a node compatible with
#     "ibm,edk2-compat-v1". This patch switches to calling secvar_ops->format(),
#     which in the case of OPAL/powernv means opal_secvar_format(), which
#     searches the device tree for a node compatible with "ibm,secvar-backend"
#     and checks its "format" property. These are equivalent, as skiboot creates
#     a node with both "ibm,edk2-compat-v1" and "ibm,secvar-backend" as
#     compatible strings.)
