* 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.

Initialize debug agent.

|

This function is used to set up debug environment to support source level debugging.
|
|
If certain Debug Agent Library instance has to save some private data in the stack,
|
|
this function must work on the mode that doesn't return to the caller, then
|
|
the caller needs to wrap up all rest of logic after InitializeDebugAgent() into one
|
|
function and pass it into InitializeDebugAgent(). InitializeDebugAgent() is
|
|
responsible to invoke the passing-in function at the end of InitializeDebugAgent().
|
|
|
|
If the parameter Function is not NULL, Debug Agent Library instance will invoke it by
|
|
passing in the Context to be its parameter.
|
|
|
|
If Function() is NULL, Debug Agent Library instance will return after setup debug
|
|
environment.

@param[in] Context Context needed according to InitFlag; it was optional.
