Compile u-boot

U-Boot is the interface between X-loader and Kernel Image. Wrong u-Boot could disable your USB port and other things. If you want to use GPIO, you can also enable GPIO in u-Boot. The beagleboard x-loader looks for u-boot.bin file on your MMC card. If none was found, the beagleboard will use the default NAND u-boot.bin file, which could have the USB disabled.
