Yes; the BSP for this platform is not yet released as far as I know.

At this moment I think your best bet is the Freescale evaluation board.

For i.MX we have many supported boards; you can see the full list at
our Release Notes[1].

1. http://freescale.github.io/doc/release-notes/1.5/

The right SoC is very project specific so it is hard to give a good
advise; regarding possible evaluation boards you have many available
and I'd say for you to try to choose one with support on this BSP so
it easy your initial development.

I hope this gives you some pointers where to start.
