Patch from Lennert Buytenhek This patch adds support for the Intel ixp23xx series of CPUs. The ixp23xx is an XSC3 based CPU with 512K of L2 cache, a 64bit 66MHz PCI interface, two DDR RAM interfaces, QDR RAM interfaces, two gigabit MACs, two 10/100 MACs, expansion bus, four microengines, a Media and Switch Fabric unit almost identical to the one on the ixp2400, two xscale (8250ish) UARTs and a bunch of other stuff. This patch adds the core ixp23xx support code, and support for the ADI Engineering Roadrunner, Intel IXDP2351, and IP Fabrics Double Espresso platforms.
