The latter has a dtb appended. But I can't recall the x530
specifically needing to be different to the other platforms... sure
enough all the a385 boards the time the x530 was added used

I think the real source of the discrepancy is that the addition of the
x530 board was in flight at the same time as ca1a4c863232 ("mvebu:
select boot device at SoC level"). I don't know of any reason
specifically that the x530 needs to be different. If I get a chance
I'll try it without a custom kwbimage.cfg.
