Subject: jffs2: convert to ROOTFS_TARGET infrastructure
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bd36a7273a6fa2d21589a1ab6e99bb231e0e868e;p=buildroot.git

jffs2: convert to ROOTFS_TARGET infrastructure

We also remove the BR2_TARGET_ROOTFS_JFFS2_OUTPUT option, that could
be used to specify an alternate name for the generated image file.
