MdeModulePkg/ResetSystemRuntimeDxe: Add platform filter and handler
Add support for platform specific reset filters and platform specific reset handlers to ResetSystem(). A filter may modify the reset type and reset data and call ResetSystem() with the modified parameters. A handler performs the reset action. The support for platform specific filters and platform specific handlers is based on the Reset Notification feature added to the UEFI 2.7 Specification. Platform specific reset filters are processed first so the final reset type and reset data can be determined. In the DXE Phase The UEFI Reset Notifications are processed second so all UEFI Drivers that have registered for a Reset Notification can perform any required clean up actions. The platform specific reset handlers are processed third. If there are no registered platform specific reset handlers or none of them reset the platform, then the default reset action based on the ResetSystemLib is performed. In the PEI Phase, filters and handlers are registered through the following 2 PPIs that are based on EFI_RESET_NOTIFICATION_PROTOCOL. * gEdkiiPlatformSpecificResetFilterPpiGuid * gEdkiiPlatformSpecificResetHandlerPpiGuid In the DXE Phase, filters and handlers are registered through the following 2 Protocols that are based on EFI_RESET_NOTIFICATION_PROTOCOL. * gEdkiiPlatformSpecificResetFilterProtocolGuid * gEdkiiPlatformSpecificResetHandlerProtocolGuid Cc: Liming Gao <liming.gao@intel.com> Reviewed-by: Ruiyu Ni <ruiyu.ni@intel.com> Reviewed-by: Star Zeng <star.zeng@intel.com> Contributed-under: TianoCore Contribution Agreement 1.1 Signed-off-by: Michael D Kinney <michael.d.kinney@intel.com>
