[U-Boot] U-boot customized

[Graeme Russ <graeme.russ@gmail.com>]

Hi Allyson,

A) Please keep the mailing list Cc'd - I don't know much about ARM and
nothing about the at91rm9200 - I'm just trying to be helpful :)

B) Please don't top-post

OK, so what you are saying is u-boot-1.1.6 from git.denx.de without any
additional modifications works fine, but U-Boot 2011.03 from git.denx.de
without any additional patches does not?

If this is the case, then you are likely going to get some pretty good
support from the ML as that would mean there is a regression in mainline
code that needs to be fixed...

Are you familiar with 'git' at all?

git has a very useful tool called 'git bisect' which basically asks for the
ID of a known 'Good commit' (in this case u-boot-1.1.6) and a known 'Bad
Commit' (2011.3). It will then find the commit halfway between and check it
out - You then compile and test and tell git if that commit was 'Good' or 'Bad'

This process will repeat until you find the commit that caused the breakage
- Post that commit ID to the mailing list and somebody should get around to
looking at it
