You should use a specific U-Boot version, so that we're sure we'll
continue to use the same tested version over time. See other defconfigs:

wandboard_defconfig:BR2_TARGET_UBOOT=y
wandboard_defconfig:BR2_TARGET_UBOOT_BOARDNAME="wandboard"
wandboard_defconfig:BR2_TARGET_UBOOT_CUSTOM_VERSION=y
wandboard_defconfig:BR2_TARGET_UBOOT_CUSTOM_VERSION_VALUE="2016.09.01"

Thanks!
