hw/intc/arm_gicv3: Add state information
Add state information to GICv3 object structure and implement arm_gicv3_common_reset(). This commit includes accessor functions for the fields which are stored as bitmaps in uint32_t arrays. Signed-off-by: Pavel Fedin <p.fedin@samsung.com> Reviewed-by: Shannon Zhao <shannon.zhao@linaro.org> Tested-by: Shannon Zhao <shannon.zhao@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1465915112-29272-7-git-send-email-peter.maydell@linaro.org [PMM: significantly overhauled: * Add missing qom/cpu.h include * Remove legacy-only state fields (we can add them later if/when we add legacy emulation) * Use arrays of uint32_t to store the various distributor bitmaps, and provide accessor functions for the various set/test/etc operations * Add various missing register offset #defines * Accessor macros which combine distributor and redistributor behaviour removed * Fields in state structures renamed to match architectural register names * Corrected the reset value for GICR_IENABLER0 since we don't support legacy mode * Added ARM_LINUX_BOOT_IF interface for "we are directly booting a kernel in non-secure" so that we can fake up the firmware-mandated reconfiguration only when we need it ] Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Shannon Zhao <shannon.zhao@linaro.org>
