Since you've applied similar patch from Peng, this one is not needed
anymore and can be dropped.
There are however few pieces that are present in this patch not picked
up in any other patch like doc update, single flash.bin, etc.
I saw that Patrick Wildt had "single flash.bin" part submitted in [1],
which would also be beneficial to have in 2022.01 for consistency, and
would allow me to update imx8mq_evk machine in meta-freescale Yocto
layer so it can be finally built with upstream BSP and 2022.01. If you
can pick it up saw well - that would be ideal!
The rest I will extract and send as separate patches after 2022.01.
