These patches add support for the Nokia RX-51/N900 to U-Boot. Rather than totally replace NOLO (which could be dangerous) I instead create a combined image containing u-boot and a Linux kernel, and then flash this like a regular kernel. U-Boot loads first, stores the environment, and then checks for boot files on the SD card, if present. If the bootfiles are not found, it will instead load the appended kernel image. This should in theory be totally transparent.
