so this function gets called from s3c_pm_check_restore via s3c_pm_run_sysram, and it runs the given memory resource, checking it against the stored CRC to make sure that memory is restored. literally its whole job. 🔥

and it tries to skip as many of the areas used during the suspend process as it can. iconic efficiency behavior, ngl. ✨
