/** @file\r
  This code abstracts the CPU IO Protocol which installed by some platform or chipset-specific\r
  PEIM that abstracts the processor-visible I/O operations.\r
\r
  Note: This is a runtime protocol and can be used by runtime drivers after ExitBootServices().\r
  It is different from the PI 1.2 CPU I/O 2 Protocol, which is a boot services only protocol\r
  and may not be used by runtime drivers after ExitBootServices().\r

// Protocol and the PI 1.2 CPU I/O 2 Protocol.  The Framework one is a runtime\r

// The PI one is not runtime safe, so it is a boot services only protocol and may\r
// not be used by runtime drivers after ExitBootServices().\r
