+Abstract:
+
+ Processor or Compiler specific defines and types for AArch64.
+ We are using the ANSI C 2000 _t type definitions for basic types.
+ This it technically a violation of the coding standard, but they
+ are used to make EfiTypes.h portable. Code other than EfiTypes.h
+ should never use any ANSI C 2000 _t integer types.
