This set of patches allows to complete platform responder to handle
platform events (set events, event messages, state sensors reading, state
effecters) and fru messages from the BMC.
Specific astbmc features (watchdog timer, Real Time Clock, Opal IPMI
calls) are also supported.

To enable the new PLDM features, add CONFIG_PLDM as a parameter:
  make .... CONFIG_PLDM=1

This patch set should be applied on top of these previous sets:
- Implement virtual flash content using PLDM.
- Import external libraries for MCTP/PLDM protocols.
- Implement MCTP and PLDM features.
