Commit d04ceb3fc2 moved phys_addr_t
definitions to include/asm-powerpc/types.h. However, arch/ppc 440
builds had a duplicate definition in include/asm-ppc/mmu.h that caused
the build to fail.
This removes the duplicate definition in arch/ppc.

Right now TLB entry 0 ist used as UART0 mapping for the early debug
output (via CONFIG_SERIAL_TEXT_DEBUG). This causes problems when many
TLB's get used upon Linux bootup (e.g. while PCIe scanning behind
bridges and/or switches on 440SPe platforms). This will overwrite the
TLB 0 entry and further debug output's may crash/hang the system.
This patch moves the early debug UART0 TLB entry from 0 to 62 as done
in arch/powerpc. This way it is in the "pinned" area and will not get
overwritten. Also the arch/ppc/mm/44x_mmu.c code is now synced with the
newer code from arch/powerpc.

This adds a vdso_base element to the mm_context_t for 32-bit compiles
(both for ARCH=powerpc and ARCH=ppc). This fixes the compile errors
that have been reported in arch/powerpc/kernel/signal_32.c.

The e200 core is a Book-E core (similar to e500) that has a unified L1 cache
and is not cache coherent on the bus. The e200 core also adds a separate
exception level for debug exceptions. Part of this patch helps to cleanup a
few cases that are true for all Freescale Book-E parts, not just e500.

CONFIG_PTE_64BIT & CONFIG_PHYS_64BIT are not currently consistently used in
the code base. Fixed up the usage such that CONFIG_PTE_64BIT is used when we
have a 64-bit PTE regardless of physical address width. CONFIG_PHYS_64BIT is
used if the physical address width is larger than 32-bits, regardless of PTE
size.
These changes required a few sub-arch specific ifdef's to be fixed and the
introduction of a physical address format string.

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!
