U-Boot loader for Banana Pi.

To install this bootloader, follow the instructions in http//linux-sunxi.org/Bootable_SD_card#Bootloader

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.
