[PATCH v4 0/4] Introduce Platform Firmware Runtime Update and Telemetry drivers

[Chen Yu]

The PFRU(Platform Firmware Runtime Update) kernel interface is designed
to interact with the platform firmware interface defined in the Management
Mode Firmware Runtime Update specification[1]. The primary function of
PFRU is to carry out runtime updates of the platform firmware, which
doesn't require the system to be restarted.  It also allows telemetry data
to be retrieved from the platform firmware.
