+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).

+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.

+From: Rod Whitby <rod@whitby.id.au>
+Date: Tue, 29 Jan 2008 23:17:42 +1030
+Subject: [PATCH] leds: Add new driver for the LEDs on the Freecom FSG-3
+
+The LEDs on the Freecom FSG-3 are connected to an external
+memory-mapped latch on the ixp4xx expansion bus, and therefore cannot
+be supported by any of the existing LEDs drivers.
+
+Signed-off-by: Rod Whitby <rod@whitby.id.au>
