The at91sam9x5 family is an ARM926 based SoC family from Atmel.
five different products are available: sam9g15, sam9g25, sam9g35
sam9x25 and sam9x35.
Evaluation Kits are composed of a CPU Module and a carrier board (with
optional screen).
The use of the Device Tree is reducing the amount of code needed for
an AT91 based SoC: sam9x5 are the first AT91 SoC that only rely on
DT for their hardware configuration.
