> This "nosmp" is intended for imx6solo on a SMP kernel, which asks SMP kernel to act as UP kernel.  If kernel supports to detect the uni-processor or multi-processor with cores number from SCU, this parameter is not necessary . But it is nice to have.  How do you think?

is this a real mx6solo processor on this board, or is it a dual-lite
that you only wants to use a single core to 'simulate' a solo?
