If possible, I would like if this series went for U-Boot 2024.10 release. The heavy stuff to support DDR speed change is already in, this just adds the ability to do it with reset button instead of console command (which is inconvenient for most users). On Omnia, the user can select factory reset type by pressing the reset button on the rear panel and holding it. The front LEDs light on in sequence, representing a counter. Every ~2.5 second another LED lights on. When only the first LED is on, the board will do a standard reboot. Then different kinds of factory reboot will happen for reset types 1 to 7 (when 1, 2, ... or 7 LEDs are on) [1]. This series adds another reset type, number 10, which will make the board boot in 1333H DDR speed mode, and also write this setting to EEPROM, so that subsequent boots will also train in 1333H mode. The user can set back the default mode with the `eeprom` U-Boot command, or with the `omnia-eeprom` Linux command.
