Hi All,
For those of you that are not tracking IRC/forums:
I've ported U-Boot to dragonboard.
For now it has to be chain-loaded from fastboot (you can flash it to "boot" partition or boot with fastboot).
Basic things are already supported: - USB host controller - eMMC/SD (a bit slow) - Some gpio's/leds - Serial port - Booting Linux
It can be helpful for people working on kernel, or just for people that prefer u-boot to fastboot.
You can get it from my github repo: https://github.com/hallor/u-boot
Most recent stable code is located on 'dragonboard' branch, there also tags created once I release something important.
As there are currently no issues I'm aware of - I'm working on cleaning-up the code for mainline, but if someone finds a bug or missing (important) functionality - please let me know.
Best Regards, Mateusz
