From abde3b56cebc611391a3e3ec63172acefea4daae Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Tue, 26 Aug 2014 15:39:51 -0700 Subject: arm64: Add support for secure monitor Secure monitor runs at EL3 and is responsible for jumping to the payload at specified EL and also to manage features like PSCI. Adding basic implementation of secure monitor as a rmodule. Currently, it just jumps to the the payload at current EL. Support for switching el and PSCI will be added as separate patches.
