> Add a psci-reboot-mode driver, and define two types of PSCI resets,
> predefined-resets and vendor-specific resets. Predefined-resets are
> defined by psci driver and vendor-specific resets are defined by SoC
> vendors, under the psci:reboot-mode node of SoC device tree.

> Register the driver with the reboot-mode framework to interface these
> resets to userspace. When userspace initiates a supported command, pass
> the reset arguments to the PSCI driver to enable command-based reset.
>
> This change allows userspace to issue supported PSCI reset commands
> using the standard reboot system calls while enabling SoC vendors to
> define their specific resets for PSCI.
