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.
