+From: Rod Whitby <rod@whitby.id.au>
+Subject: [PATCH] ixp4xx: Add support for the Freecom FSG-3 board (Patch #4874)
+
+The Freecom-FSG3 is a small network-attached-storage device with the
+following feature set:
+
+* Intel IXP422
+* 4MB Flash (ixp4xx flash driver)
+* 64MB RAM
+* 4 USB 2.0 host ports (ehci and ohci drivers)
+* 1 WAN (eth1) and 3 LAN (eth0) ethernet ports
+ * Supported by the open source ixp4xx ethernet driver
+* Via VT6421 disk controller (libata and sata-via drivers)
+ * Internal hard disk (PATA supported, SATA not yet supported)
+ * External SATA port (not yet supported)
+* ISL1208 RTC chip
+* Winbond 83782 temp sensor and fan controller
+* MiniPCI slot
+
+The ixp4xx_defconfig is also updated to support this device (the
+leds-fsg driver is to be submitted separately via the leds tree after
+this initial support is merged, as it depends on header gpio defines).
+
+Signed-off-by: Rod Whitby <rod@whitby.id.au>
+
+PATCH FOLLOWS
+KernelVersion: v2.6.25-rc6-74-g264e3e8
+---
+
+Updated to correct all issues found by RMK.
+
+The front power button calls ctrl_alt_del() and the rear reset button
+now calls machine_restart() directly.
