[ARM] 5570/1: at91: Support for at91sam9g10: core chip & board support
From: Hong Xu <hong.xu@atmel.com>
Here are the modification to at91sam9261 files dedicated to the support of
at91sam9g10. This direction has been adopted to minimize code duplication.
All at91sam9261 drivers are enabled in _devices and board- files. Modificaton
to peripherals that support at91sam9g10 will be added in future patches.
