U-Boot documentation

[monnier]

Where's the boot information?
Things like:
- How to build U-Boot
- How to install it (how it's found, in which order various devices are tried to find the cmd.boot file, ...).
- What's supported by the U-Boot build (is it supposed to show something on HDMI, if not why not? Does it support USB keyboards connected via USB hubs? What partition types does it know about?)
- If the U-Boot code be merged into the upstream U-Boot? If yes, why do you direct people to your own code (what's the difference), and if not when will it be merged upstream?

@monnier: Did you find something interesting from the official Web site of U-Boot ?
https://u-boot.org/


@"Forum's Moderators: I am also VERY interested into the U-Boot topic, could you relay these questions to the developers team, please ?

Best regards,

Ever struggled with U-Boot's mysteries? I have! I spent days trying to get HDMI output working, only to realize the default configuration lacked the necessary driver. Is your build showing nothing on HDMI? Check your device tree and enabled drivers! My own build initially diverged due to specific hardware needs, but I'm actively working on upstreaming the relevant patches.
