   1 /* Armv8-A RAS 1.1 extension system registers.
   2
   3 Please note that early Armv8-a architectures do not officially support RAS
   4 extension.
   5
   6 Certain use cases require developers to enable only more generic architecture
   7 (e.g. -march=armv8-a) during system development. Users must use RAS extension
   8 registers bearing in mind that system they use must support it.  */
