[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.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

+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

+
+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.
