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. CQ-DEPEND=CL:218300 BUG=chrome-os-partner:30785 BRANCH=None TEST=Compiles succesfully and secure monitor loads and runs payload on ryu Change-Id: If0f22299a9bad4e93311154e5546f5bae3f3395c Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Original-Commit-Id: 5e40a21115aeac1cc3c73922bdc3e42d4cdb7d34 Original-Change-Id: I86d5e93583afac141ff61475bd05c8c82d17d926 Original-Signed-off-by: Furquan Shaikh <furquan@google.com> Original-Reviewed-on: https://chromium-review.googlesource.com/214371 Original-Tested-by: Furquan Shaikh <furquan@chromium.org> Original-Reviewed-by: Aaron Durbin <adurbin@chromium.org> Original-Commit-Queue: Furquan Shaikh <furquan@chromium.org> Reviewed-on: http://review.coreboot.org/9080 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
