ARM Git Tree (at91sam9g45 patches)

Greetings,

I'm working with the Atmel at91sam9g45-ekes board which is new.  I was
wondering if there was a git tree with the current ARM patches that
contains the at91sam9g45 code?  Russell lists "Applied" patches at
http://www.arm.linux.org.uk/developer/patches/ .  Where are these
applied to?  If there isn't a tree, is there an elegant way to get the
latest patch sets that I could apply to Linus's tree?

Thank you,

Rob
