+U-Boot loader for BeagleBone and BeagleBone Black.
+
+To install this bootloader, copy the files MLO and bb-uboot.img to the FAT
+partition on an SD card or the eMMC. Normally this is partition 1, but
+different partitions can be set with U-Boot environment variables.
+
+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 uboot.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 bbubldr on the FAT partition
+ to address 0x88000000, and launches it.
+
+Note: prefixing the boot files with 'bb' allows building
+images with boot bits for more than one board.
+
+For information about running FreeBSD on BeagleBone or BeagleBone Black, see
+ https://wiki.freebsd.org/FreeBSD/arm/BeagleBone
+
+For general information about U-Boot see WWW: http://www.denx.de/wiki/U-Boot
