you may want to see [1] how this was done for OMAP4 (which has a SMP
cortex A9)-> we can discuss how to setup cortex_a9 in mainline u-boot.
My thought would be: cpu/arm_cortexa9 - considering that a9 cores could
be from 1 to 4 or so if my memory serves right -> btw, I wonder how SMP
handling is done in u-boot today..
