 /**
  * This file defines the Secure Monitor Call (SMC) message protocol used for
  * service layer driver in normal world (EL1) to communicate with secure
  * monitor software in Secure Monitor Exception Level 3 (EL3).
  *
  * This file is shared with secure firmware (FW) which is out of kernel tree.
  *
  * An ARM SMC instruction takes a function identifier and up to 6 64-bit
  * register values as arguments, and can return up to 4 64-bit register
  * value. The operation of the secure monitor is determined by the parameter
  * values passed in through registers.
  *
  * EL1 and EL3 communicates pointer as physical address rather than the
  * virtual address.
  *
  * Functions specified by ARM SMC Calling convention:
  *
  * FAST call executes atomic operations, returns when the requested operation
  * has completed.
  * STD call starts a operation which can be preempted by a non-secure
  * interrupt. The call can return before the requested operation has
  * completed.
  *
  * a0..a7 is used as register names in the descriptions below, on arm32
  * that translates to r0..r7 and on arm64 to w0..w7.
