I had a look at what boards are left in u-boot at the moment and found 41
board numbers for machines that can still boot (older) kernels using ATAG.
Almost all of them require DT in the mainline kernel already though, the
only two exceptions are:

* pxa270-colibri (getting removed from u-boot now), and
* davinci da850evm (kernel has both DT and a board file)

All other SoCs on my list already have no u-boot support at all.
For davinci, u-boot supports the same three boards as the kernel
using DT, on PXA the colibri has been the last one standing for a
while now.
