This patch is based on the port by Mihai Georgin (see linkstation.c for Copyright information) and implements support for LinkStation / KuroBox HD and HG PPC models from Buffalo Technology.
Notice for users: this is pretty much a barebone port. To support network you need at least the patch for rtl8169.c or dc2114x.c driver depending on your model. Ideally you also need supporting 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 and the accompanying network driver patches provide a fully functional u-boot with a network console on your system.
