# KERNEL_DEVICETREE follows the pattern of
# 'rockchip/${SOC_FAMILY}-${BOARD}.dtb' which is required when compiling
# the kernel so the kernel's Makefile can find the device tree
#
# when using extlinux with a fitImage the device tree is contained in the
# fitImage
#
# however for non-fitImages it is not found at
# $UBOOT_EXTLINUX_FDTDIR/rockchip/$KERNEL_DEVICETREE but rather at
# $UBOOT_EXTLINUX_FDTDIR/$KERNEL_DEVICETREE therefore we need to strip off
# the 'rockchip/' part for extlinux non-fitImage builds
