4649913ea5 ppc4xx: Add common ppc4xx linker script
This linker script can be used by all PPC4xx platforms. It works for
PPC405 and PPC440 platforms. Boards which need a board specific linker
script can override this default linker script in board/*/config.mk.

495a0dde7f cpu/ppc4xx/config.mk: Make a needlessly deffered expansion immediate.
This will reduce the build time.

e7670f6c1e PPC: Use r2 instead of r29 as global data pointer
R29 was an unlucky choice as with recent toolchains (gcc-4.2.x) gcc
will refuse to use load/store multiple insns; instead, it issues a
list of simple load/store instructions upon function entry and exit,
resulting in bigger code size, which in turn makes the build for a
few boards fail.

Use r2 instead.

efa35cf12d ppc4xx: Clean up 440 exceptions handling
- Introduced dedicated switches for building 440 and 405 images required
  for 440-specific machine instructions like 'rfmci' etc.

- Exception vectors moved to the proper location (_start moved away from
  the critical exception handler space, which it occupied)

- CriticalInput now serviced (with default handler)

- MachineCheck properly serviced (added a dedicated handler and return
  subroutine)

- Overall cleanup of exceptions declared with STD_EXCEPTION macro (unused,
  unhandled and those not relevant for 4xx were eliminated)

- Eliminated Linux leftovers, removed dead code
