Hi Andy,
I fixed the commit description according to your suggestions and used git send-email.
Regards!
When powering Intel Edison module with 3.3V, the "reboot" command makes the module stuck. If the module is powered at a greater voltage, like 4.4V(as the Edison Mini Breakout board does), reboot works OK.
This patch copies the behaviour from the official Intel Edison BSP, where "IPCMSG_COLD_RESET" message was sent to SCU by default at reboot time.
In the official BSP, sending the "IPCMSG_COLD_BOOT" message instead of "IPCMSG_COLD_RESET" was possible, by using a kernel command line parameter.
