From d323af9e3d903d981b42f954844a95a6bfef91ab Mon Sep 17 00:00:00 2001 From: Daniel Boulby Date: Fri, 6 Jul 2018 16:54:44 +0100 Subject: [PATCH] Rework page table setup for varying number of mem regions Change arm_setup_page_tables() to take a variable number of memory regions. Remove coherent memory region from BL1, BL2 and BL2U as their coherent memory region doesn't contain anything and therefore has a size of 0. Add check to ensure this doesn't change without us knowing.
