There is nothing to patch on X15[1]. there is no MSECURE pin on X15.
there are three RTCs on X15: MCP, TPS and DRA7-RTC. TPS has no use for
RTC, in fact has no capability of having a backup battery - which pretty
much (at least IMHO) removes real world use of TPS as a RTC in a
non-networked world.. but anyways, lets keep X15 and uevm seperate -
they dont share much in this context.
