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?
