This file declares Read-only Variable Service PPI
+ These services provide a lightweight, read-only variant of the full EFI variable services. The
+ reason that these services are read-only is to reduce the complexity of flash management. Also,
+ some implementation of the PEI may use the same physical flash part for variable and PEIM
+ storage; as such, a write command to certain technologies would alter the contents of the entire part,
+ thus making the in situ PEIM execution not follow the required flow.
