Subject: [PATCH 5/6] ARM: BCM5301X: Specify all RAM by including an extra
|
|
block

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.
