As it was already suggested by Russell King and Arnd Bergmann ( https://lkml.org/lkml/2013/5/16/133 ), moxart and gemini seem to be the only platforms using CPU_FA526, and instead of pointing arm_pm_idle to an empty function from platform code, it makes sense to remove WFI code from the processor specific idle function.
Note: moxart boots and prints to UART without this patch, but input is broken.
