From c45414b542ee31283bd5954211facbee217f0322 Mon Sep 17 00:00:00 2001 From: Loic Devulder Date: Tue, 25 Sep 2018 16:30:35 +0200 Subject: [PATCH] ARM: meson: Extend mem_map to support 3GiB of RAM The current mem_map definition for Meson SoCs has support for up to 2GiB of RAM. According to S905, S905X, S912 and S805X datasheets the DDR region is set from 0x00000000 to 0xBFFFFFFF, so mem_map's definition should be changed accordingly. It is also needed to be able to boot Khadas VIM2 board with S912 SoC.
