From dcc3ecc940e95cb6a97dbea203d3680f67910b59 Mon Sep 17 00:00:00 2001 From: Patrick Georgi Date: Thu, 28 Jan 2016 15:00:54 +0100 Subject: arch/arm64: Override bl31 timestamp with coreboot build timestamp If coreboot's build process is reproducible (eg. using the latest git timestamp as source), bl31 is, too. This requires an arm-trusted-firmware side merge first (in progress) and an update of our reference commit for the submodule, but it also doesn't hurt anything because it merely sets a variable that currently goes unused.
