Sorry; let me be more specific; any objection to moving device initialization to *after* relocation to RAM. I'm not asking about removing console output.
Yes, I *do* object. Please see previous messages.
You know how much I'm fighting over a few bytes memory footprint here and there, but this is something that is so vitally important for porting U-Boot to green hardware that I am happy to "waste" whatever it needs in terms of memory for this feature.
But why does this affect device initialization? To get to running in RAM; there needs to be three things: RAM initialized correctly, code copied and basic console output for progress metering. Why do devices not related to these three things matter? Why can't they be deferred until after relocation to RAM?
I say don't get distracted with non-essential peripherals when the first priority is to get into RAM.
