From 32d333f2f068c77024631e54b3edc1c992d964a4 Mon Sep 17 00:00:00 2001 From: Daniel Allred Date: Fri, 2 Sep 2016 00:40:23 -0500 Subject: ti_omap5_common: mark region of DRAM protected on HS parts If the ending portion of the DRAM is reserved for secure world use, then u-boot cannot use this memory for its relocation purposes. To prevent issues, we mark this memory as PRAM and this prevents it from being used by u-boot at all.
