ARM: ixp4xx: enable multiplatform support After all the work that Linus Walleij did on this platform, it can be part of a generic kernel build as well. Note that there are known bugs in little-endian mode on ixp4xx, and no other ARMv5 platform at this point supports big-endian mode, or is likely to in the future, so there is limited practical value in this, but it helps with build testing and ixp4xx little-endian support may get fixed in the future.

Support for Intel's IXP4XX (XScale) family of processors.
Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

ARM: ixp4xx: Add device tree boot support This adds a minimal support for booting IXP4xx systems from device tree. We have to add hacks to the QMGR, NPE and notably also ethernet and watchdog drivers so that they don't crash the platform: these drivers are unconditionally starting to grab regions of statically remapped IO space with no concern of the device model or other platforms. We will go in and properly fix these drivers as we go along but for now this hack gets us to a place where we can start working on proper device tree support for these platforms.
