Hi,
unfortunately the patch [1] is only the first part to get DM_VIDEO
running properly on tbs2910 for u-boot-2020.10. With this, I get a valid
video output signal, but no actual video console output, only a blank
screen.
After some debugging, no with access to a HDMI monitor, the problem

The printf() string produces a warning about %d not matching size_t. Fix
it and put the format string on one line to avoid a checkpatch warning.

Recent versions of Chrome OS do not have a kernel in the root disk, to
save space.
With the improvements to the 'zboot' command it is fairly easy to load
the kernel from the raw partition. Add instructions on how to do this.

At present the setup block is always obtained from the image
automatically. In some cases it can be useful to use a setup block
obtained elsewhere, e.g. if the image has already been unpacked. Add an
argument to support this and update the logic to use it if provided.

This command is currently monolithic and does not support scripts which

At present the 'zboot' command does everything in one go. It would be

In preparation for this, move the 'state' of the command into a struct.

Hi Nicolas,
I do have USB MSD boot working with at least two USB flash drives
successfully.
I now tried using a USB NVMe enclosure (ICY BOX with a JMicron chip in
it). It seems that U-Boot has troubles enumerating the device at first,
but "usb reset" helps:
