17/// ## Platform Communications Channel (PCC)
18///
19/// The platform communication channel (PCC) is a generic mechanism for OSPM to communicate with an entity in the platform (e.g. a platform controller, or a Baseboard Management Controller (BMC)).
20/// Neither the entity that OSPM communicates with, nor any aspects of the information passed back and forth is defined in this section.
21/// That information is defined by the actual interface that that employs PCC register address space as the communication channel.
22///
23/// PCC defines a new address space type (PCC Space, 0xA), which is implemented as one or more independent communications channels, or subspaces.
