From c1ec34763811d2465c030bfa2fa8e240b36d60ce Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Tue, 2 Oct 2018 21:42:49 +0200 Subject: [PATCH] ARM: rmobile: Mark 4-64GiB as DRAM on Gen3 Mark area 0x1_0000_0000 - 0x10_0000_0000 as DRAM on Gen3 as the chip is capable of addressing that and U-Boot can make use of it. This patch prevents exception when accessing those areas.
