From 745a75faac970ec5dd35472412ddb94e888e4198 Mon Sep 17 00:00:00 2001 From: Julius Werner Date: Mon, 11 May 2015 16:45:56 -0700 Subject: arm64: Add support for using ARM Trusted Firmware as secure monitor This patch adds support for integrating the runtime-resident component of ARM Trusted Firmware (github.com/ARM-software/arm-trusted-firmware) called BL31. It expects the ARM TF source tree to be checked out under $(top)/3rdparty/arm-trusted-firmware, which will be set up in a later patch. Also include optional support for VBOOT2 verification (pretty hacky for now, since CBFSv1 is just around the corner and will make all this so much better). BRANCH=None BUG=None TEST=Booted Oak with ARM TF and working PSCI (with additional platform patches).
