That's 32MB, not 32kB.  Better fix this :-)

It's a shame you can't use unit addresses for these since
you use "dcr-reg" instead of "reg".  Oh well.

Maybe rename the node to "memory-controller"?

Is this thing _only_ addressable over DCRs?  Weird.

Remove "device_type", change name to "dma-controller"?

You forgot "ibm,ebc" here.
