This adds the device trees and minimal code needed to run
U-Boot on Broadcom Northstar SoCs.

This is needed to properly boot the D-Link DIR-890L router
as it refuse to directly boot compressed kernels bigger
than 2MB, and well our compressed kernel is bigger than
2MB so let's put in U-Boot.

While it is a bit tailored to this usecase (it can probably
also be used with the DIR-885L without modifications) it
forms a base that can be used to support more Northstar
boards.

I have this working with DIR-890L and OpenWrt:
https://dflund.se/~triad/krad/dlink-dir-890l/

ChangeLog v3->v4:
- Rewrote the algorithm detection patch to be more
  careful so as to fix Tom's regression.
ChangeLog v1->v3:
- Bundle with the iproc NAND and nand base pacthes
  as the iproc patch is a prerequisite.
- Jump from v1->v3 as the other patches was at version
  v3.

It is a bit of a mystery to me who can merge this patches...
BRCM custodian?

Hello Linus,

Could you, please, add documentation describing installation under
doc/board/broadcom/.

Best regards

Heinrich
