[ARM] 5572/1: at91: Support for at91sam9g45 series: core chip & board support
Here are the at91 specific files dedicated to the at91sam9g45 series. They mimic the traditional at91 way of managing chips & boards. The first board that embeds at91sam9g45 chip is the AT91SAM9G45-EKES. In the future, the main board for this 9g45 series will be the AT91SAM9M10G45-EK (I choose this last name for the board file). Simple drivers are enabled in _devices and board- files. Newer peripheral support will be added in future patches. Incuded peripherals support (for now): - USART - SPI - Ethernet - NAND flash - LCD - gpio/joystick/buttons - leds and pwm Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com> Acked-by: Andrew Victor <linux@maxim.org.za> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
