I'm working on OMAP and others, and Jeremy is working on i.MX51
targeting real product.  Visible progress has been slow since there is
a lot more back end infrastructure work than I was expecting to get
the ppc, sparc and microblaze code merged into a common code base and
to move away from the whole of_platform bus stuff (so that regular
platform drivers work).  The alternative would be to add yet another
duplicate copy of device tree code to ARM which I will not do, and I
know you wouldn't accept anyway.  :-)
