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).

  27 KernelVersion: v2.6.25-rc6-74-g264e3e8

  29
  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.
