at least gpu (AMD/FSL proprietary) & iirc video codecs (not all proprietary 
but far from mainline unless I missed something). In fact in the end these 
boards were using Freescale's kernel.

I confirm that's a good target for removal as our i.MX51 customers are 
actually using cpuimx51sd (actually without 3D & codecs actually but not 
everyone need these peripherals in industrial applications). Moreover, if all 
the drivers are mainlined we will be able to use dt if we want to upgrade 
cpuimx51.

Thanks,
Eric
