OK posted a patch for the SBC-T3730 with minimal support also for
SBC-3530 and SBC-3517 that should boot far enough to start adding
more devices. Paul, care to try it on the CM-T3517, the patch is:

[PATCH] ARM: dts: Add support for sbc-3xxx with cm-t3730

Let's hope there's two smsc911x devices also on the 3517 based board,
otherwise it should have a completely separate .dts file.
