board: Add new Broadcom Northstar board
This adds a simple Northstar "BRCMNS" board to be used with
the BCM4708x and BCM5301x chips.
The main intention is to use this with the D-Link DIR-890L
and DIR-885L routers for loading the kernel into RAM from
NAND memory using the BCH-1 ECC and using the separately
submitted SEAMA load command, so we are currently not adding
support for things such as networking.
The DTS file is a multiplatform NorthStar board, designed to
be usable with several NorthStar designs by avoiding any
particulars not related to the operation of U-Boot.
If other board need other ECC for example, they need to
create a separate DTS file and augment the code, but I don't
know if any other users will turn up.
