you seem to be mixing poky distro with OE-Core here. As a whole the
patch seems like adding support for ramfs based images. If you intend
to just have images specific to poky then this patch
belongs to OE-Core but if you generalize it enough that non
tiny users can also leverage this then it certainly is good
for OE-Core.
