OK, I've reproduced the problem now, and is indeed real. I'll whip up a
patch.
The very very odd thing is that imx31-dt.c is only compiled if
CONFIG_MACH_IMX31_DT, and imx_v6_v7_defconfig doesn't specify a value
for that option, so it's disabled when I "make imx_v6_v7_defconfig". If
I manually enable the option via "make menuconfig", then I do see this
problem.
