This is the same direction that "we" are headed in as well.  For a
given core, it is more or less possible to generate one kernel that
works on any number of  SOCs and boards that use that core.  The only
difference is which device tree it is given.

So all you need to do is have your boot loader create a device tree
from scratch.  If you're using U-Boot, then you can already do this by
making the appropriate libfdt calls.  Otherwise, you should probably
add libfdt to your boot loader.
