From 1efe2578c00e18cfc409f2ecfd95118f95a0d69c Mon Sep 17 00:00:00 2001 From: Tristan Shieh Date: Thu, 9 Aug 2018 15:14:15 +0800 Subject: mediatek: Map SRAM as secure and cached memory This patch changes the mapping of SRAM from non-secure to secure. Without this patch, mmu_config_range() can not work when MMU is enabled. The new config is still in non-secure cache since TTB section is allocated in SRAM which is mapped as non-secure.
