    ARM: imx: add smp support for imx7d · e34645f4
    Anson Huang authored
    Add SMP support for i.MX7D, including CPU hotplug support, for
    systems where TFA is not present.
    
    The motivation for bringing up the second i.MX7D core inside the kernel
    is that legacy vendor bootloaders usually do not implement PSCI support.
    
    This is a significant blocker for systems in the field that are running old
    bootloader versions to upgrade to a modern mainline kernel version, as only
    one CPU of the i.MX7D would be brought up.
    
    Bring up the second i.MX7D core inside the kernel to make the migration
    path to mainline kernel easier for the existing iMX7D users.
