+U-Boot loader for NanoPi Neo.
+
+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 distroboot command knows how to load FreeBSD loader(8)
+ * By default, it loads ubldr.bin (PIE) from file ubldr.bin on the FAT
+   partition to address 0x42000000, and launches it. If ubldr.bin is
+   not found, it falls back on ubldr
+
+For information about running FreeBSD on NanoPi Neo, see
