5. mach-at91rm9200

(1) copy files

at91sam926x_time.c

at91sam9260.c

at91sam9260_devices.c

board-sam9260ek.c

(2) modify Makefile

Add:

# AT91SAM9260 board-specific support

obj-$(CONFIG_MACH_AT91SAM9260EK) += board-sam9260ek.o

(3) modify Kconfig

1). at "comment "AT91SAM9260 Board Type"" following, append:

config MACH_AT91SAM9260EK

bool "Atmel AT91SAM9260-EK Evaluation Kit"

depends on ARCH_AT91SAM9260

help

Select this if you are using Atmel‘s AT91SAM9260-EK Evaluation Kit.

<http://www.atmel.com/dyn/products/tools_card.asp?tool_id=3933>

2). at "comment "AT91 Feature Selections"" above, append:

# ----------------------------------------------------------

comment "AT91 Board Options"

config MTD_AT91_DATAFLASH_CARD

bool "Enable DataFlash Card support"

depends on (ARCH_AT91RM9200DK || MACH_AT91RM9200EK \

|| MACH_AT91SAM9260EK || MACH_AT91SAM9261EK || MACH_AT91SAM9263EK)

help

Enable support for the DataFlash card.

config MTD_NAND_AT91_BUSWIDTH_16

bool "Enable 16-bit data bus interface to NAND flash"

depends on (MACH_AT91SAM9261EK || MACH_AT91SAM9260EK || MACH_AT91SAM9263EK)

help

On AT91SAM926x boards both types of NAND flash can be present

(8 and 16 bit data bus width).

3). at "comment "AT91 Feature Selections"" inside, append:

config AT91_SLOW_CLOCK

bool "Suspend-to-RAM uses slow clock mode (EXPERIMENTAL)"

depends on PM && EXPERIMENTAL

help

Select this if you wish to put the CPU into slow clock mode

while in the "Suspend to RAM" state, to save more power.

6. kernel cfg

ebd9260.cfg or

sbc9260.cfg.
