[PATCH 1/5] at91: Basic support for at91sam9g10: header files

From: Nicolas Ferre
Date: Thu Jun 18 2009 - 11:13:07 EST


From: Hong Xu <hong.xu@xxxxxxxxx>

AT91sam9g10 is an ARM 926ej-s SOC. It is an evolution of the at91sam9261 with a
faster clock speed: 266/133MHz.

Here is the basic header file support for this product.
