Upgrade the power and reset button handling for the DSMG600:
From 67e494e3e03ef807255f084800d8658b89ff5fec Mon Sep 17 00:00:00 2001
From: Rod Whitby <rod@whitby.id.au>
Date: Tue, 29 Jan 2008 10:00:25 +1030
Subject: ixp4xx: Button updates for the dsmg600 board (Patch #4769)
* Remove the superfluous declaration of ctrl_alt_del().
* Convert GPIO and IRQ handling to use the <asm/gpio.h> api.
* Perform the reset on the release of the power button, so that
NAS devices which have been set to auto-power-on (by bridging
the power button) do not continuously power cycle.
NAS devices which have been set to auto-power-on (by solder
bridging the power button) do not continuously power cycle.
* Remove all superflous constants from dsmg600.h

Subject: ixp4xx: Button and LED updates for the nas100d board (Patch #4768)
* Convert GPIO and IRQ handling to use the <asm/gpio.h> api.
* Perform the reset only after the power button has been held down
for at least two seconds. Do the reset on the release of the power
button, so that NAS devices which have been set to auto-power-on (by
bridging the power button) do not continuously power cycle.

* Remove all superflous constants from nas100d.h
* Add LED constants to nas100d.h while we're there.
Also, update the board LED setup code to use constants.
* Update the board LED setup code to use those constants.

Subject: ixp4xx: Use leds-gpio driver instead of IXP4XX-GPIO-LED driver
These are the only three boards to use the IXP4XX-GPIO-LED driver, and
they can all use the new leds-gpio driver instead with no change in
functionality.

Date: Tue, 29 Jan 2008 10:03:19 +1030
Subject: ixp4xx: Ethernet support for the nslu2 and nas100d boards
Enables the new ixp4xx qmgr and npe drivers in ixp4xx_defconfig.
Sets up the corresponding platform data for the nslu2 and nas100d
boards, and reads the ethernet MAC address from the internal flash.
Tested on both little-endian and big-endian kernels.

From: Rod Whitby <rod@whitby.id.au>
Subject: ixp4xx: Merge nslu2-power.c into nslu2-setup.c (Patch #4807)
There is no reason to have power control in a separate file from the
board setup code. Merge it back into the board setup file, removing
superfluous header includes and removing superfluous constants from
the machine header file.

From: Rod Whitby <rod@whitby.id.au>
Subject: ixp4xx: Merge dsmg600-power.c into dsmg600-setup.c (Patch #4809)
There is no reason to have power control in a separate file from the
board setup code. Merge it back into the board setup file and remove
superfluous header includes.
