    arm64: kernel: add PM build infrastructure · 166936ba
    Lorenzo Pieralisi authored
    This patch adds the required makefile and kconfig entries to enable PM
    for arm64 systems.
    
    The kernel relies on the cpu_{suspend}/{resume} infrastructure to
    properly save the context for a CPU and put it to sleep, hence this
    patch adds the config option required to enable cpu_{suspend}/{resume}
    API.
    
    In order to rely on the CPU PM implementation for saving and restoring
    of CPU subsystems like GIC and PMU, the arch Kconfig must be also
    augmented to select the CONFIG_CPU_PM option when SUSPEND or CPU_IDLE
    kernel implementations are selected.
