BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3108 In preparation for a new interface to be added to the MemEncryptSevLib library that will be used in SEC, create an SEC version of the library. This requires the creation of SEC specific files. Some of the current MemEncryptSevLib functions perform memory allocations which cannot be performed in SEC, so these interfaces will return an error during SEC. Also, the current MemEncryptSevLib library uses some static variables to optimize access to variables, which cannot be used in SEC.
