[edk2-devel] [PATCH v1 1/1] MdePkg: Add PCCT table signature definition

[Krzysztof Koch]

Acpi63.h contains definitions describing the Platform Communications
Channel Table's (PCCT) structure. However, a macro for the table's
signature is missing.

This patch adds the definition of Platform Communications Channel
Table's signature.
