The pds_fwctl driver doesn't know what RPC operations are available
in the firmware, so also doesn't know what scope they might have. The
userland utility supplies the firmware "endpoint" and "operation" id values
and this driver queries the firmware for endpoints and their available
operations. The operation descriptions include the scope information
which the driver uses for scope testing.

pds_fwctl: initial driver framework2025-03-21T23:57:55+00:00Shannon Nelsonshannon.nelson@amd.com2025-03-20T19:44:10+00:00urn:sha1:4d09dd11d7d0e7e7f535c0abc7de19b9da6612e9
Initial files for adding a new fwctl driver for the AMD/Pensando PDS
devices. This sets up a simple auxiliary_bus driver that registers
with fwctl subsystem. It expects that a pds_core device has set up
the auxiliary_device pds_core.fwctl
