The solution on the commit you mentioned is related to the
i.MX8MN/i.MX8MP boot ROM implementation, and it works there.

What confuses me about João's patch is that it was not tested against
the mainline U-Boot.

Can U-Boot mainline boot over serial download on i.MX95?

Adding Tim, as he has been trying to get USB boot to work with i.MX95.

I don't have access to any i.MX95 board to try it myself, so I
appreciate some help here.
