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.
