reboot-mode: add support for reboot mode control A new driver uclass is created to handle the reboot mode control. The new uclass driver is updating an environment variable with the configured reboot mode. The mode is extracted from a map provided at initialization time. The map contains a list of modes and associated ids. Signed-off-by: Nandor Han <nandor.han@vaisala.com> Reviewed-by: Simon Glass <sjg@chromium.org> 2021-06-10 13:56:43 +00:00			`#`

reboot-mode: read the boot mode from GPIOs status A use case for controlling the boot mode is when the user wants to control the device boot by pushing a button without needing to go in user-space. Add a new backed for reboot mode where GPIOs are used to control the reboot-mode. The driver is able to scan a predefined list of GPIOs and return the magic value. Having the modes associated with the magic value generated based on the GPIO values, allows the reboot mode uclass to select the proper mode.

reboot-mode: read the boot mode from RTC memory RTC devices could provide battery-backed memory that can be used for storing the reboot mode magic value. Add a new reboot-mode back-end that uses RTC to store the reboot-mode magic value. The driver also supports both endianness modes.
