To support mt8183 power saving during suspend to RAM, this patch loads SPM firmware to support SPM suspend. SPM needs its own firmware to do these power saving in the right timing under correct conditions.

2019-09-14arm64: Uprev Arm TF and adjust to BL31 parameter changesJulius Werner
This patch uprevs the Arm Trusted Firmware submodule to the new upstream master (commit 42cdeb930). Arm Trusted Firmware unified a bunch of stuff related to BL31 handoff parameters across platforms which involved changing a few names around. This patch syncs coreboot back up with that. They also made header changes that now allow us to directly include all the headers we need (in a safer and cleaner way than before), so we can get rid of some structure definitions that were duplicated. Since the version of entry point info parameters we have been using has been deprecated in Trusted Firmware, this patch switches to the new version 2 parameter format. NOTE: This may or may not stop Cavium from booting with the current pinned Trusted Firmware blob. Cavium maintainers are still evaluating whether to fix that later or drop the platform entirely. Tested on GOOGLE_KEVIN (rk3399).
