4 Subject: [PATCH 5/6] ARM: BCM5301X: Specify all RAM by including an extra
5 block
6 MIME-Version: 1.0
7 Content-Type: text/plain; charset=UTF-8
8 Content-Transfer-Encoding: 8bit

10 The first 128 MiB of RAM can be accessed using an alias at address 0x0.
11
12 In theory we could access whole RAM using 0x80000000 - 0xbfffffff range
13 (up to 1 GiB) but it doesn't seem to work on Northstar. For some reason
14 (hardware setup left by the bootloader maybe?) 0x80000000 - 0x87ffffff
15 range can't be used. I reproduced this problem on:
16 1) Buffalo WZR-600DHP2 (BCM47081)
17 2) Netgear R6250 (BCM4708)
18 3) D-Link DIR-885L (BCM47094)
19
20 So it seems we're forced to access first 128 MiB using alias at 0x0 and
21 the rest using real base address + 128 MiB offset which is 0x88000000.
