This patch removes all self references and fixes references to files
in the now defunct arch/ppc64 tree.  I think this accomplises
everything wanted, though there might be a few references I missed.

Cleanup PPC40x eval boards (bubinga, walnut and sycamore) to support U-Boot
as bootloader.  The OpenBIOS bd_info struct is not used in the kernel
anymore (only U-Boot now).

uImage (U-Boot) tested on walnut, sycamore and bubinga
zImage (OpenBIOS) tested on sycamore, bubinga and ebony

Fix 44x early serial debugging for big RAM configurations (more than 512M).
 We cannot use default OpenBIOS virtual mapping, because it interferes with
pinned TLB entry.

While we are at it, move early UART mapping to TLB slot 0, so it can
survive longer during boot process (slot 1 is used by the first ioremap
call, effectively killing UART mapping if it occupies this slot).  Also,
change UART TLB entry size to 4K (256M is too much for a bunch of registers
:).  Squash some warnings on the way.

Tested on Ebony and Ocotea with 1G of RAM.

Thanks to Scott Coulter <scott.coulter@cyclone.com> for diagnosing this
problem.

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!
