Subject: This patch renames the Atmel atstk1002 target board to a more generic
 atstk100x name. This to make it easier to add support for other CPU-boards
 than atstk1002. Submitted by Hans-Christian Egtvedt

+Subject: [PATCH 1/1] Add gpio_mouse board setup to atstk1000 board
+
+This patch adds a gpio_mouse_platform_data to the atstk1000 board code and
+registers a gpio_mouse platform_device. This will enable a GPIO mouse on header
+J1 on GPIO of the ATSTK1000 development kit. The board code is enabled/disabled
+in menuconfig.
+
+By connecting J1 (GPIO) to J25 (SWITCH) you can use the following keys to
+simulate a mouse:
+
+SW0: right
+SW1: down
+SW2: up
+SW3: left
+SW5: right button
+SW6: middle button
+SW7: left button
