and here is an example of accessing the ST_CLO from linux
though i never bothered adding model detection, so you have to un-comment the right one
in this case, its comparing ST_CLO (which starts when the SoC leaves reset) and /proc/uptime (which starts when linux boots)
the difference is then how long it took for the firmware to boot and pass control to linux
