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.

They were named incorrectly most likely due to copy & paste mistake.

Every device tested so far got UART0 (at 0x18000300) working as serial
console. It's most likely part of reference design and all vendors use
it that way.
It seems to be easier to enable it by default and just disable it if we
ever see a device with different hardware design.
