So here is my question: Where do you see the most potential to optimize u-boot?

I already have two bullets on my list (just some ideas - maybe totally unrealistic *g*):

• Use Hardware specific copy commands
• build the checksum while moving the kernel to RAM

This shouldn't be a matter of opinion/guess work. You should instrument U-Boot first and find out where the time is really being spent. Otherwise you run the classic risk of optimizing something that isn't really a problem.

Good luck, I look forward to seeing the results of your analysis.
