You're changing 64-bit Armada files here, but in the cover letter you
mention that this patchset only addresses 32-bit mvebu DT files. So
why are you making these changes here?

One more comment below...

Why is spi0 aliased now to "cp0_spi1"? In the Kernel DT files I see
this:

		spi0 = &spi0;
		spi1 = &cp0_spi0;
		spi2 = &cp0_spi1;
...
			spi0: spi at 510600 {

Thanks,
Stefan
