I just started to work on my bachelor thesis. It is about "Linux boot-up time optimization". The past days I spend analyzing what consumes the most time in the boot process.
I found that u-boot takes pretty much as long as the whole Linux kernel (the one we are using).
I started digging into the source and I think I have a big picture of what is going on. I already learned from the mailing list that it is a good idea to start a discussion early if you plan to change something and want it upstream. At this point of my thesis I'am free to choose where I start - only string attached is that if it is platform specific it has to be TI OMAP3.
So here is my question: Where do you see the most potential to optimize u-boot?
Setting stdin, stdout and stderr takes a lot of time (IIRC ~500ms). Which IMO is useless on a bootloader without LCD support.
eh ? those are still used with serial consoles. unless you're talking about some driver that is specific to the OMAP3 and/or a board. -mike
