google/oak: Add soc ARM Trusted Firmware support
We define a mechanism to pass board specific parameters to BL31. The idea is BL31 doesn't need to have the board revision knowledge, it only needs to process the board specific parameters to initialize and control specific hardware. In this way, we can support different boards with same BL31 binary. BRANCH=none BUG=none TEST=booted on oak-rev2 and oak-rev3 boards, and confirmed they got different board arguments in ARM TF Change-Id: I0df2c6d7d1ffac7d443511c3317c142efeb5701e Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Original-Commit-Id: 0f9a4a2776110c5ddc113f0d605d4337d5773ace Original-Change-Id: I985d9555238f5ac5385e126479140b772b36bac8 Original-Signed-off-by: Jimmy Huang <jimmy.huang@mediatek.com> Original-Reviewed-on: https://chromium-review.googlesource.com/292678 Original-Commit-Ready: Yidi Lin <yidi.lin@mediatek.com> Original-Tested-by: Yidi Lin <yidi.lin@mediatek.com> Original-Reviewed-by: Julius Werner <jwerner@chromium.org> Reviewed-on: https://review.coreboot.org/13101 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
