This patch is based on the port by Mihai Georgian (see linkstation.c for Copyright information) and implements support for LinkStation / KuroBox HD and HG PPC models from Buffalo Technology, whereby HD is deactivated at the moment, pending network driver fixing. Notice to users: this is pretty much a barebone port. Support for network on HG models is already in the U-Boot mainline, but you might also want patches to switch fan / phy modes depending on the negotiated ethernet parameters. This patch also doesn't support console switching, booting EM mode, Buffalo specific ext2 magic number. So, if you want to use any of those, you need additional patches. Otherwise this patche provides a fully functional u-boot with a network console on your system. Signed-off-by: Guennadi Liakhovetski <lg@denx.de>
