As of today eglfs is incapable of supporting multiple screens. It will always use fb0, which is not ideal since boards like the iMX6 are often used in a multi-display setup.

Both eglfs and the iMX6 hooks need to be enhanced. At minimum the framebuffer device/index has to be configurable, so that, similarly to linuxfb, the display to be used can be specified on the command-line. Once that's done, we need to consider discovering and exposing all of the available FBs as QPlatformScreens. This might introduce some unforeseen difficulties, though, and needs some investigation.
