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