-+
-+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)

++ You should take care, that $ACTION is "add" and $SUBSYSTEM is "firmware"

++
++Solution 2)
++ create a char-dev: "mknod /dev/misc/npe c 10 184"
++ cat the Microcode into it:
++ cat /usr/lib/hotplug/firmware/NPE-* > /dev/misc/npe
++ 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 !
++   Compile it with "gcc -Wall IxNpeMicrocode.c -o IxNpeMicrocode" on your host.
++   The resulting images can be moved to "/usr/lib/hotplug/firmware"
++
++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.
