I object firstly on principle that you don't need the DT support to allow this, it could have been done years ago if anyone had taken the time to do it. > 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.

We could have had the same for Samsung's entire range if a bit of work had been applied to do things like PAGE_OFFSET and replaceable IRQ controllers. > In any case, this is the least of the worries when you're wanting to > build multiple SoCs into the same kernel image.
