[U-Boot] at91sam source tree to use

[Moises Beck]

Hello,
      I would like to customize an u-boot source tree to use in an 
at91sam9263 embedded CPU board. But I am in doubt if I should use the 
main u-boot source tree or the at91 fork tree (and now orphaned one) ? 
What are the main differences between the main and at91 forked source 
trees ? I saw that a lot of at91sam9263 related code exists in tha main 
tree...

thanks,
Moises
