    ARM: EXYNOS: Move code from hotplug.c to platsmp.c · 6f0b7c0c
    Krzysztof Kozlowski authored
    Cleanup a little the SMP/hotplug code for Exynos by:
    1. Moving completely all functions from hotplug.c into the platsmp.c;
    2. Deleting the hotplug.c file.
    
    After recent cleanups (e.g. 75ad2ab2 "ARM: EXYNOS: use
    v7_exit_coherency_flush macro for cache disabling") there was only CPU
    power down related code in hotplug.c file.
    
    Rationale behind the code movement and benefits:
    1. The file platsmp.c is the only user of code located in hotplug.c.
       Keeping code in hotplug.c required declaring exynos_cpu_die() in common.h.
       Such dependencies and mentioned exynos_cpu_die() declaration can be
       removed.
    2. In next patches exynos_set_delayed_reset_assertion() will be
       introduced. This function will be called by:
        - cpu_leave_power (hotplug.c),
        - platform_do_lowpower (hotplug.c),
        - exynos_boot_secondary (platsmp.c).
    
    Merging hotplug.c into platsmp.c leads to simpler and cleaner code with
    less dependencies between files.
    
    The commit only moves code around with one additional observable change:
    the hotplug.c was compiled with custom CFLAGS (-march=armv7-a). These
    CFLAGS are not necessary any more.
