So - different .init_machine() calls, needed to simplify the board
files as of now. (Patch from Lee Jones.)

But ultimately I would expect that the init_machine calls to be the same
with a DT based machine. This goes back to do we add DT to existing
boards or create a new clean DT machine and add to it as boards are
converted?

Yes that should be the ultimate goal. So the current per-board
init functions register the I2C, MMC (SDI), SPI, UART and
regulator devices etc. So then these drivers need to be patched to
get their board/platform data from DT first.

In that case we should hold this patch off and only keep it for
internal testing until all necessary drivers are ready and patched
so we can replace all board files with a single DT-based one,
instead of this compromise solution.

I would not hold off. You only need to have a minimal set that's enough
to boot.

Is this what everybody else does?

That was the the consensus in Budapest in May. It's much cleaner to
start with a new board file and then ultimately just delete the old
ones. But it's really up to the board/SOC maintainer.
