Change in coreboot[master]: arm64: Uprev Arm TF and adjust to BL31 parameter changes - coreboot-gerrit

2 Aug 2019

Hello Patrick Rudolph, Hung-Te Lin, Patrick Georgi,
I'd like you to do a code review. Please visit
https://review.coreboot.org/c/coreboot/+/34676
to review the following change.
Change subject: arm64: Uprev Arm TF and adjust to BL31 parameter changes
......................................................................
arm64: Uprev Arm TF and adjust to BL31 parameter changes
This patch uprevs the Arm Trusted Firmware submodule to the new upstream
master (commit 3ee48f40f5).
Arm Trusted Firmware unfinied 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.
(Also rename arm_tf.c to bl31.c because I'm getting annoyed with the
auto-completion clashes it keeps causing.)
