=====

A library to support secure monitor mode implemented by ARM v7 Security
extensions.

API:

sm_sched_secure - Switch to Secure OS
sm_sched_nonsecure - Switch to Nonsecure OS

sm_register_entity - Register fastcall/stdcall handlers for an entity
(See ARM document DEN 0028A)

sm_get_boot_args - get a pointer/reference to boot parameter block
sm_put_boot_args - release a reference to boot parameter block
(See bootloader spec)

Note that this library provides an implementation for the weak symbol
"platform_reset". It also assumes that r0 contains the size of memory reserved
for the secure OS.
