I suspected the same thing on my wandboard with the wrong-endian
prefetch abort problem, and noticed that u-boot was violating some of
the imx6 rules for voltage regulation, so with great hopes for a fix I
added some code to the freebsd early kernel init to increase the voltage
slightly and get all 3 regulators in range with each other according to
what the manual said... it didn't help.
