Registers a CPU Feature.
- @param GetConfigDataFunc CPU feature get configuration data function. This
- is an optional parameter that may be NULL. If NULL,
- then the most recently registered function for the
- CPU feature is used. If no functions are registered
- for a CPU feature, then the CPU configuration data
- for the registered feature is NULL.
- @param SupportFunc CPU feature support function. This is an optional
- parameter that may be NULL. If NULL, then the most
- recently registered function for the CPU feature is
- used. If no functions are registered for a CPU
- feature, then the CPU feature is assumed to be
- supported by all CPUs.
- @param InitializeFunc CPU feature initialize function. This is an optional
- parameter that may be NULL. If NULL, then the most
- recently registered function for the CPU feature is
- used. If no functions are registered for a CPU
- feature, then the CPU feature initialization is
- skipped.
- @param ... Variable argument list of UINT32 CPU feature value.
- Values with no modifiers are the features provided
- by the registered functions.
- Values with CPU_FEATURE_BEFORE modifier are features
- that must be initialized after the features provided
- by the registered functions are used.
- Values with CPU_FEATURE_AFTER modifier are features
- that must be initialized before the features provided
- by the registered functions are used.
- The last argument in this variable argument list must
- always be CPU_FEATURE_END.
