In case of MCU with multiple firmware slots support, change of active slot requires reset. This obviously results in MCU entering the serial recovery mode in bootloader, with 5 sec timeout, which in case of UART based MCUs isn't automatically detected and handled in the same way as USB based devices (hotplug). Starting host side support script when the MCU is waiting for MCUmgr commands during recovery is wrong. This fixes the problem by requesting UART based MCU to boot the firmware after active slot change followed by reset. While at it, change also how single slot type MCUs are handled during upgrade (always request reset after the upgrade). Signed-off-by: Piotr Dymacz <pepe2k@gmail.com>
