I have one issue with starting the kernel on i.MX7. The architected timer does not work. In U-Boot I found arch/arm/imx-common/syscounter.c in which the system counter is initialized. I just copied the code and it works, but I wonder what I am doing here. I can't find any documentation in the Reference Manual and also the 8MHz tick rate for the architected timer seems to fall from the sky. Do you have any additional documentation?
