    Initialise cpu ops after enabling data cache · 12e7c4ab
    Vikram Kanigiri authored
    The cpu-ops pointer was initialized before enabling the data cache in the cold
    and warm boot paths. This required a DCIVAC cache maintenance operation to
    invalidate any stale cache lines resident in other cpus.
    
    This patch moves this initialization to the bl31_arch_setup() function
    which is always called after the data cache and MMU has been enabled.
    
    This change removes the need:
     1. for the DCIVAC cache maintenance operation.
     2. to initialise the CPU ops upon resumption from a PSCI CPU_SUSPEND
        call since memory contents are always preserved in this case.
