-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.

-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.
