Do we really need console output before U-Boot has initialised SDRAM?
Yes, we do. This is one of the things I definitely want to keep as it saved me lots of hours before. I won't give this up lightly.
It's important for board bringup, and it's also very useful that you always see it when booting - if U-Boot hangs because a RAM or a flash or a XXX error, you always KNOW it because the last thing you see on the console is "RAM" or "FLash" or "XXX". This is a very important feature.
I guess I should write some design principles for U-Boot...
Best regards,
