From a252ccd3d2327556c6331e926abd82f4bfe4ce52 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Wed, 7 Dec 2016 08:56:54 +0100 Subject: [PATCH] ARM: dts: BCM5301X: Specify all RAM by including an extra block MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The first 128 MiB of RAM can be accessed using an alias at address 0x0. In theory we could access whole RAM using 0x80000000 - 0xbfffffff range (up to 1 GiB) but it doesn't seem to work on Northstar. For some reason (hardware setup left by the bootloader maybe?) 0x80000000 - 0x87ffffff range can't be used. I reproduced this problem on: 1) Buffalo WZR-600DHP2 (BCM47081) 2) Netgear R6250 (BCM4708) 3) D-Link DIR-885L (BCM47094) So it seems we're forced to access first 128 MiB using alias at 0x0 and the rest using real base address + 128 MiB offset which is 0x88000000.
