Secure Monitor Calls

The secure monitor provides two top level handlers of which each provides a range of sub handlers.

Secure Monitor Calls follow the ARM SMC calling convention:

Bit number	Bit mask	Description
31	0x80000000	Set to 0 means Yielding Call; Set to 1 means Fast Call.
30	0x40000000	Set to 0 means SMC32 convention; Set to 1 means SMC64.
29-24	0x3F000000	Service Call ranges.
23-16	0x00FF0000	Must be zero.
15-0	0x0000FFFF	Function number within the range call type.

Cryptography related functions.
