The theory is with DT is that machine_is_xxx() is no longer required,
because they're fully described by DT.  Such a kernel should not care
whether it's running on board XYZ or ABC because the differences are
wrapped up in the DT description of it.

Moreover, DT boards do not have machine IDs - their machine ID is "~0"
which will be universal for all DT using platforms.  So machine_is_xxx()
really has no meaning at all when using DT.  Basically, DT makes machine
IDs obsolete.

Agreed.
