I do not want to add mxc_cpu_type and cpu_is_mx6q() stuff, so I intend to remove early_initcall there, and let imx31/35_soc_init() explicitly calls mxc_init_l2x0().I'm changing my mind (so quickly). It turns out we will fall into a number of other traps if we build imx6q with imx3 without mxc_cpu_type set up for imx6q, arch_idle(), __imx_ioremap(), etc. So for now, I want to add mxc_cpu_type for imx6q to cooperate with all these traps.
I'm fine with reducing the usage of cpu_is_* macros up to the point when we don't need them anymore. But as you already found out, it's better to do this seperately.
