Subject: imx6: images: add bootfs.tar.gz build artifact
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d1005862c2c0a298d2ff492f531aa266857dbde8;p=openwrt%2Fstaging%2Fyousong.git

imx6: images: add bootfs.tar.gz build artifact

In order to create a bootable block storage device, both bootfs and rootfs
tarballs are required. However, our current scheme does not export a bootfs
tarball so add the packaging of it here.
