Migrate all ixp4xx devices to the bitbanging I2C bus driver utilizing
the arch-neutral GPIO API (linux/i2c-gpio.h).
Tested by the nslu2-linux and openwrt projects in public firmware releases.

This trivial patch updates the nslu2 and nas-100d headers to
remove pointless GPIO defines, and updates nslu2-setup.c
accordingly. In addition minor style cleanups to some comments
are included.

This patch is required as the frequency fixup in nslu2_init does not
run sufficiently early in the boot sequence to take effect. In addition
the dsmg600 setup code behaviour has been improved such that a
'fixup' routine is avoided.

Patch from Rod Whitby
This patch implements NEW_LEDS support for the Linksys NSLU2. The
NSLU2 has four LED indicators, which are the only form of output for
an unmodified device - there is no keyboard or display on an NSLU2.
For an NSLU2 which has been modified to bring out the serial port
console, it is important to register that device first separately, to
enable debugging of other device support.

ARM patch 3226/1 (IXP4xx runtime expansion bus window size configuration)
forgot to update mach-ixp4xx/nslu2-setup.c which leads to the following
compilation error. Update NSLU2 flash support following patch 3226/1.

Patch from Nicolas Pitre
This field is redundent since it must be equal to PHYS_OFFSET anyway.
Now that no code uses it anymore, mark it deprecated and remove all
initializations from the tree.

Patch from Alessandro Zummo
This patch adds support for the LinkSys NSLU2 running with
both big and little-endian kernels. The LinkSys NSLU2 is
a cost engineered ARM, XScale 420 based system similar to
the the Intel IXDP425 evaluation board. It uses the
IXP4XX ARCH.
While this patch applies independently of other patches
the resultant kernel requires further patches to successfully
use onboard devices, including the onboard flash. Since these
patches are independent of this one they will be submitted
separately.
A defconfig is not included here because not all of
the required drivers are actually in the kernel.
We intend to provide one as soon as the patches
will be incorporated in mainstream.
This patch is the combined work of nslu2-linux.org
