On this point, I strongly object, especially as I'm one who uses the
existing non-DT multiplatform support extensively. It's really not
a problem for what you're trying to achieve.

I think what you're proposing is a totally artificial restriction.
There's no problem with a kernel supporting DT and non-DT together.
We've proven that many many times. I prove it _every_ night that my
build and boot system runs - the OMAP LDP boots a multiplatform kernel
just fine without DT.

In any case, this is the least of the worries when you're wanting to
build multiple SoCs into the same kernel image. See my previous reply
concerning that.
