mediatek: use U-Boot FAT environment support for Banana Pi R2
Instead of building in a default environment which loads our environment from the FAT partition.... just ask U-Boot to do it. Submitted upstream at https://patchwork.ozlabs.org/project/uboot/list/?series=184688 Signed-off-by: David Woodhouse <dwmw2@infradead.org>
