[edk2] [PATCH v2] SourceLevelDebugPkg: Use Pcd for the revision of transfer protocol
Posted by Hao Wu 7 years, 3 months ago 
V2 changes:
Instead of using a global variable, use a Pcd for transfer protocol
revision.

Previously, the revison of the debug agent transfer protocol is
reflected by a macro.

This commit introduces a Pcd to reflect the revision in order to avoid the
comparision of two macros, which will generate a constant result
detected by code checkers.

2. Please describe the PcdTransferProtocolRevision layout. Upper 2-byte for
major revision, lower-2-byte for minor revision. 0x0004 stands for 0.4.
