[AVR32] Make STK1000 mux settings configurable 



This adds some STK1002-specific config options covering the jumper settings,
so the kernel can automatically be configured to include the relevant devices.

One of them replaces the previous internal SW2_DEFAULT setting; SPI config
is affected by two of the jumpers; and a fourth one switches between LCD and
the second Ethernet connector.  (There's more that to be done.)

config BOARD_ATSTK1002_CUSTOM

	bool "Non-default STK-1002 jumper settings"

	help

	  You will normally leave the jumpers on the CPU card at their

	  default settings.  If you need to use certain peripherals,

	  you will need to change some of those jumpers.



if BOARD_ATSTK1002_CUSTOM



config BOARD_ATSTK1002_SW1_CUSTOM

	bool "SW1: use SSC1 (not SPI0)"

	help

	  This also prevents using the external DAC as an audio interface,

	  and means you can't initialize the on-board QVGA display.



config BOARD_ATSTK1002_SW2_CUSTOM

	bool "SW2: use IRDA or TIMER0 (not UART-A, MMC/SD, and PS2-A)"

	help

	  If you change this you'll want an updated boot loader putting

	  the console on UART-C not UART-A.



config BOARD_ATSTK1002_SW3_CUSTOM

	bool "SW3: use TIMER1 (not SSC0 and GCLK)"

	help

	  This also prevents using the external DAC as an audio interface.



config BOARD_ATSTK1002_SW4_CUSTOM

	bool "SW4: use ISI/Camera (not GPIOs, SPI1, and PS2-B)"

	help

	  To use the camera interface you'll need a custom card (on the

	  PCI-format connector) connect a video sensor.



config BOARD_ATSTK1002_SW5_CUSTOM

	bool "SW5: use MACB1 (not LCDC)"



config BOARD_ATSTK1002_SW6_CUSTOM

	bool "SW6: more GPIOs (not MACB0)"



endif	# custom



config BOARD_ATSTK1002_SPI1

	bool "Configure SPI1 controller"

	depends on !BOARD_ATSTK1002_SW4_CUSTOM

	help

	  All the signals for the second SPI controller are available on

	  GPIO lines and accessed through the J1 jumper block.  Say "y"

	  here to configure that SPI controller.
