* Add timestamps to UART log messages.
* Add support for [tryboot] conditional the bootloader EEPROM
config file.
See: https://github.com/raspberrypi/rpi-eeprom/issues/454
* Fix MAX_RESTARTS parameter
See: https://github.com/raspberrypi/rpi-eeprom/issues/576
* Add recovery_reboot option to config.txt for rpiboot which causes
the system to reboot after updating the bootloader.
* Improve secure-boot OTP provisioning logging.
* Fix setting to enable secure-boot mode on Pi4B
* Switch to building the Pi4 firmware from the common Pi4/Pi5
mainline release. This doesn't change the Pi4 features
but should make it quicker to release bug fixes in common code.
* Fix issue that caused the TRYBOOT flag to be lost in secure-boot mode.
* dtoverlay: Use %u when converting u32s to strings
See: https://github.com/raspberrypi/linux/issues/6039
* Improved debug messages for secure-boot.
* Generate the bootloader diagnostics qrcode at run time.
The EEPROM release names were changed to follow the naming
in raspi-config some time ago. Since the firmware directory
is being renamed to be chip specific for Pi5 support it's
good time to swap the symlink / release names.
