Patch from Rod Whitby This patch adds support for a new arm/ixp4xx machine - the Iomega NAS 100d network attached storage product. The NAS100D is a consumer device containing a 266MHz Intel IXP420 processor, 16MB of flash, 64MB of RAM, a 160Gb internal IDE hard disk, and 802.11b/g wireless on an Atheros mini-PCI card. Work on porting the latest 2.6.x kernel to this device is being done by the NSLU2-Linux project (the same team who maintains the port to the Linksys NSLU2 device). In particular, the majority of this patch was authored by Alessandro Zummo, based on the work done for MACH_NSLU2 support by the NSLU2-Linux core team of developers. MACH_NAS100D (as implemented by this patch) can be enabled in jumbo ixp4xx kernels without any affect on the other machines supported by that kernel. This patch applies cleanly against 2.6.15-rc7 and should be trivial to apply to later kernel versions. It does not depend upon any other patches.
