From: Carlo Caione <carlo@xxxxxxxxxxxx>
In the Amlogic SoCs the secure monitor calls are used for a lot of reasons:
interact with the NVMEM (efuses), check the reboot reason, set USB boot, ...
This driver defines a generic interface towards the secure monitor that can be
used by more specialized drivers to interact with the secure monitor itself
without worrying about bounce buffers managing.
Changelog:
v2:
* All the SMC function identifiers are now in a SoC-specific header file to
be included by the DTS files so the SMC commands are now defined in the DT
instead to be hardcoded into the driver
* Patchset is no longer an RFC
* Better error management and boundary checking
* s/unsigned int/u32/
* SMC call not only on CPU 0
* Fix memory leaking
* s/amlogic/meson/ in the directory names
