    arm64: Relax the kernel cache requirements for boot · c218bca7
    Catalin Marinas authored
    With system caches for the host OS or architected caches for guest OS we
    cannot easily guarantee that there are no dirty or stale cache lines for
    the areas of memory written by the kernel during boot with the MMU off
    (therefore non-cacheable accesses).
    
    This patch adds the necessary cache maintenance during boot and relaxes
    the booting requirements.
