From 36a8f8fd471ae7c6dc8a810aaa8ff8734706234e Mon Sep 17 00:00:00 2001 From: Roberto Vargas Date: Wed, 26 Jul 2017 09:23:09 +0100 Subject: reset2: Add PSCI system_reset2 function This patch implements PSCI_SYSTEM_RESET2 API as defined in PSCI v1.1 specification. The specification allows architectural and vendor-specific resets via this API. In the current specification, there is only one architectural reset, the warm reset. This reset is intended to provide a fast reboot path that guarantees not to reset system main memory.
