/**
 * 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.
