I made a single imx6 kernel work for all flavors of soc, but I can't get
rid of the WANDBOARD* configs until we have an alternate mechanism for
requesting that a given DTB (or several of them) gets compiled and
installed without being set in the kernel config.  Warner said he was
working on something to allow that.

But our plethora of arm configs isn't going to be reduced all that much.
We have 77 config files, 30 of them have FDT_DTS_FILE.  If we eliminated
all the configs that differ only in the FDT_DTS_FILE=, we'd get rid of
maybe 8 or 10 of them.
