add redboot parsing and rtl8169 fixes, enable r8169 and add the free ixp4xx ethernet driver - the later still needs fixes and testing for the gateway 7001

++Informations about the Networking Driver using the IXP4XX CPU internal NPEs
++and Queue manager.
++
++If this driver is used, the IAL (Intel Access Library) must not be loaded.
++However, the IAL may be loaded, if this Modules are unloaded:
++	ixp4xx_npe.ko, ixp4xx_qmgr.ko ixp4xx_mac.ko
++
++This also means that HW crypto accelleration does NOT work when using this
++driver, unless I have finished my crypto driver for NPE-C
++
++
++Adoption to your custom board:
++------------------------------
++use "arch/arm/mach-ixp4xx/ixdp425-setup.c" as template:
++
++in "static struct mac_plat_info" adopt the entry "phy_id" to your needs
++(Ask your hardware designer about the PHY id)
++If in doubt, try the values from the ixdp425 board.
++
++The order of "&mac0" and "&mac1" in the "struct platform_device"
++determines which of them becomes eth0 and eth1.
++
++
++The Microcode:
++---------------
++
++The Download functions below are endianess independent.
++If the image comes in wrong endianess, it is swapped automatically.
++
++Solution 1)
++ Configure "CONFIG_HOTPLUG" and "CONFIG_FW_LOADER" and configure
++ IXP4XX_NPE as module.
++ The default hotplug script will load the Firmware from
++ /usr/lib/hotplug/firmware/NPE-[ABC]
++ see Documentation/firmware_class/hotplug-script
++
++ You should take care, that $ACTION is "add" and $SUBSYSTEM is "firmware"
++ to avoid unnessecary calls:
++ test $ACTION = "remove" -o $SUBSYSTEM != "firmware" && exit
++
++Solution 2)
++ create a char-dev: "mknod /dev/ixp4xx_ucode c 10 184".
++ If you are using "udev" or busybox "mdev", they will do this
++ for you automatically during module load.
++ cat the Microcode into it:
++ cat /usr/lib/hotplug/firmware/NPE-* > /dev/ixp4xx_ucode
++ This also works if the driver is linked to the kernel
++
++Having a mix of both (e.g. solution 1 for NPE-B and solution 2 for NPE-C)
++is perfectly ok and works.
++
++The state of the NPEs can be seen and changed at:
++/sys/bus/platform/devices/ixp4xx_npe.X/state
++
++
++Obtaining the Microcode:
++------------------------
++1) IxNpeMicrocode.h in this directory:
++   Download IPL_IXP400NPELIBRARYWITHCRYPTO-2_1.ZIP from Intel
++   It unpacks the Microcode IxNpeMicrocode.c
++   Read the Licence !
++   Read the top of IxNpeMicrocode.h for more details.
++   Compile it with "gcc -Wall IxNpeMicrocode.c -o IxNpeMicrocode" on your host.
++   The resulting images can be moved to "/usr/lib/hotplug/firmware"
++   The endianeess of the written microcode can be controlled by the
++   switches -le -be. Default is big-endian.
++
++2) mc_grab.c in this directory:
++   Compile and execute it either on the host or on the target
++   to grab the microcode from a binary image like the RedBoot bootloader.
++   (big-endian images only)
