Yes, I believe it is.  I guess what I'm waiting / hoping for is someone
to patch the top-level Makefile to call $(BOARD_SIZE_CHECK) on a number
of make targets that look reasonable, throw it at travis and see what if
anything fails (and if stuff fails, ask for help to see if it's right or
investigate a bit more).  More or less, if it's a final target for
U-Boot, we should probably give BOARD_SIZE_CHECK a try.  Most of the
rules start with u-boot, but I bet the %.imx target should also do it,
and then we can drop all of that from arch/arm/mach-imx/Makefile.
