arm: mvebu: turris_omnia: Show MCU version
There are already more MCU firmware versions for Turris Omnia in production, so display git commit (version) of the MCU firmware during U-Boot startup. It will help to identify what version of MCU firmware is Turris Omnia using. MCU firmware for Turris Omnia is open source and available at website: https://gitlab.nic.cz/turris/hw/omnia_hw_ctrl It can be updated from running system via i2c bus with this tool: https://gitlab.nic.cz/turris/omnia-mcutool Signed-off-by: Pali Rohár <pali@kernel.org> Reviewed-by: Stefan Roese <sr@denx.de>
