This patch is to use the Context to indicate SMM Debug Agent support or not if InitFlag is DEBUG_AGENT_INIT_SMM. Context must point to a BOOLEAN if it's not NULL.

/**

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.
|
|
|
|
If InitFlag is DEBUG_AGENT_INIT_SMM, Context must point to a BOOLEAN if it's not
|
|
NULL, which indicates SMM Debug Agent supported or not.
|
|
|
|
@param[in] InitFlag Init flag is used to decide the initialize process.
|
|
@param[in] Context Context needed according to InitFlag; it was optional.
|
|
@param[in] Function Continue function called by debug agent library; it was
|
|
optional.
