Luiz Otavio O Souza ae95160278 Adds the U-Boot loader for Banana pi, Cubieboard and Cubieboard2.
This version is patched so that:
 * ELF and API features are enabled.
 * The default environment is trimmed to just what's needed to boot.
 * The saveenv command writes to the file u-boot.env on the FAT partition.
 * The DTB file name is chosen based on the board model and passed to ubldr
   using the fdtfile env variable. ubldr loads the DTB from /boot/dtb/ on
   the FreeBSD partition.
 * By default, it loads ELF ubldr from file ubldr on the FAT partition to
   address 0x42000000, and launches it.
