EFI MM Configuration PPI as defined in PI 1.5 specification.
|
|
|
|
This PPI is used to:
|
|
1) report the portions of MMRAM regions which cannot be used for the MMRAM heap.
|
|
2) register the MM Foundation entry point with the processor code. The entry
|
|
point will be invoked by the MM processor entry code.
