So, I'm trying to fix the problem on am335x_evm (and some family
configs) with needing SPL_OF_CONTROL enabled.  This is mostly fine just
enabling the option, except on am335x_evm itself, which is the
kitchen-sink config and overflows memory.  I've gone with switching to
SPL_OF_PLATDATA there as am335x in general has all of the U_BOOT_DRVINFO
entries it needs I believe.  But, with the following patch:

I get the following failure and I don't see how to debug this:
