From b5f05b063413245e3d29186739fb5db98d137dfd Mon Sep 17 00:00:00 2001 From: Radhey Shyam Pandey Date: Fri, 27 Sep 2013 16:52:57 +0530 Subject: [PATCH] arm: zynq : Revert TZ_DDR_RAM to secure. TZ_DDR_RAM on reset is in secure mode. Since uboot and linux runs in full TZ privilege secure mode, no need to set DDR trustzone to non-secure.
