This is my intention for the default setting to gate clock as much as possible in order to save power. This also means that when other periph added you need Turn on the clock explicitly.
Indeed, this is a good idea and respects U-boot principles: enable something only when it is needed.
So, my suggestion is:
- don't change this imximage.cfg,
- turn on the clock you need in the driver code,
Agree
