KERNEL_DEVICETREE may contain more than one DTB, the first one being the default one. Therefore, let's split on space first, to get the first DTB before stripping the directory name from it. This doesn't add support for creating multiple labels for each DTB in KERNEL_DEVICETREE. Reviewed-by: Trevor Woerner <twoerner@gmail.com> Fixes:3b51866f22

# 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
