[ARM] 4874/2: ixp4xx: Add support for the Freecom FSG-3 board
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).
