>> 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?

This is a real mx6solo processor on this board.
Your question reminders me this bootarg is indeed for simulation. In fsl release, we provide a feature to simulate the mx6dl for mx6solo. But on a real mx6solo board, this bootarg is unnecessary.
