14 * This file defines the Secure Monitor Call (SMC) message protocol used for
15 * service layer driver in normal world (EL1) to communicate with secure
16 * monitor software in Secure Monitor Exception Level 3 (EL3).
17 *
18 * This file is shared with secure firmware (FW) which is out of kernel tree.
19 *
20 * An ARM SMC instruction takes a function identifier and up to 6 64-bit
21 * register values as arguments, and can return up to 4 64-bit register
22 * value. The operation of the secure monitor is determined by the parameter
23 * values passed in through registers.
24 *
25 * EL1 and EL3 communicates pointer as physical address rather than the
26 * virtual address.
27 *
28 * Functions specified by ARM SMC Calling convention:
29 *
30 * FAST call executes atomic operations, returns when the requested operation
31 * has completed.
32 * STD call starts a operation which can be preempted by a non-secure
33 * interrupt. The call can return before the requested operation has
34 * completed.
35 *
36 * a0..a7 is used as register names in the descriptions below, on arm32
37 * that translates to r0..r7 and on arm64 to w0..w7.
