From 1d4c6c6f6cc0efe97d6962a81e309a1c040d1def Mon Sep 17 00:00:00 2001 From: Julius Werner Date: Mon, 12 Sep 2016 15:46:02 -0700 Subject: [PATCH] rockchip/rk3399: Move TTB to the end of SRAM We found that we may want to load some components of BL31 on the RK3399 into SRAM. As usual, these components may not overlap any coreboot regions still in use at that time, as is already statically checked by the check-ramstage-overlaps rule in Makefile.inc. On RK3399, the only such regions are TTB and STACK. This patch moves the TTB region back to the end of SRAM (right before STACK), so that a large contiguous region of SRAM before that remains usable for BL31. BRANCH=gru BUG=None TEST=Booted Kevin.
