* Enable DebugAgentLib to support source level debug over serial By default, source level debug is NOT enabled. ENABLE_SOURCE_DEBUG needs to be set to 1 in BoardConfig.py of each Platforms. - self.ENABLE_SOURCE_DEBUG = 1 As an initial drop, there are some limitations on APL platform. - Stage1A does not include DebugAgentLib due to Stage1A size limitation(32KB). Further optimization is required. - DebugAgentLib supports ONLY POSTMEM debugging on APL currently.
