target/linux/ixp4xx/patches-2.6.25/030-ixp4xx_fsg_board_support.patch

   1 From: Rod Whitby <rod@whitby.id.au>
   2 Subject: [PATCH] ixp4xx: Add support for the Freecom FSG-3 board (Patch #4874)
   3
   4 The Freecom-FSG3 is a small network-attached-storage device with the
   5 following feature set:
   6
   7 * Intel IXP422
   8 * 4MB Flash (ixp4xx flash driver)
   9 * 64MB RAM
  10 * 4 USB 2.0 host ports (ehci and ohci drivers)
  11 * 1 WAN (eth1) and 3 LAN (eth0) ethernet ports
  12   * Supported by the open source ixp4xx ethernet driver
  13 * Via VT6421 disk controller (libata and sata-via drivers)
  14   * Internal hard disk (PATA supported, SATA not yet supported)
  15   * External SATA port (not yet supported)
  16 * ISL1208 RTC chip
  17 * Winbond 83782 temp sensor and fan controller
  18 * MiniPCI slot
  19
  20 The ixp4xx_defconfig is also updated to support this device (the
  21 leds-fsg driver is to be submitted separately via the leds tree after
  22 this initial support is merged, as it depends on header gpio defines).

  30 Updated to correct all issues found by RMK.
  31
  32 The front power button calls ctrl_alt_del() and the rear reset button
  33 now calls machine_restart() directly.
