There is no cpuidle implemented on imx28.  I do not understand how
these options influence the result here.

I just ran a case with CONFIG_CPU_IDLE and RCU support and failed
to reproduce the warning.  Is this something specific to gpmi-nand
or we can see it with any other imx28 drivers/cases?  Sorry, I do
not have NAND flash set up on my imx28 board.
