at91sam source tree to use

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

Hello Moises,

I'm using a board of same family (at91sam9620 and at91sam9g60) and I`m using the main u-boot source tree, everything is working...
