d1c3b27525 ppc4xx: Big cleanup of PPC4xx defines
This patch cleans up multiple issues of the 4xx register (mostly
DCR, SDR, CPR, etc) definitions:

- Change lower case defines to upper case (plb4_acr -> PLB4_ACR)
- Change the defines to better match the names from the
  user's manuals (e.g. cprpllc -> CPR0_PLLC)
- Removal of some unused defines

Please test this patch intensive on your PPC4xx platform. Even though
I tried not to break anything and tested successfully on multiple
4xx AMCC platforms, testing on custom platforms is recommended.

317734966e Dual-license IBM code contributions
It was brought to our attention that U-Boot contains code derived from the
IBM OpenBIOS source code originally provided with some of the older PowerPC
4xx development boards.  As a result, the original license of this code has
been carried in the various files for a number of years in the U-Boot project.

IBM is dual-licensing the IBM code contributions already present in U-Boot
under either the terms of the GNU General Public License version 2, or the
original code license already present.

5d841fac82 ppc4xx: Move definition for PPC4xx NAND FLASH controller to header
This patch moves the definition for the PPC4xx NAND FLASH controller
(NDFC) CONFIG_NAND_NDFC into include/ppc4xx.h. This is needed for the
upcoming fix for the ECC byte ordering of the NDFC driver.

c9c11d751e ppc4xx: Add routine to retrieve CPU number
Provide a weak defined routine to retrieve the CPU number for
reference boards that have multiple CPU's.  Default behavior
is the existing single CPU print output.  Reference boards with
multiple CPU's need to provide a board specific routine.
See board/amcc/arches/arches.c for an example.

f556483734 ppc4xx: Cleanup of "ppc4xx: Optimize PLB4 Arbiter..." patch
This patch fixes some minor issues introduced with the patch:
ppc4xx: Optimize PLB4 Arbiter... from Prodyut Hazarika:

- Rework memory-queue and PLB arbiter optimization code, that the
  local variable is not needed anymore. This removes one #ifdef.
- Use consistant spacing in ppc4xx.h header (XXX + 0x01 instead
  of XXX+ 0x01). This was not introduced by Prodyut, just a
  copy-paste problem.

- Moved PLB4 Arbiter register definitions to ppc4xx.h since it is shared
  across processors (405 and 440/460)
- Optimize Memory Queue settings for PPC440SP/SPE and PPC460EX/GT/SX

4fb25a3db3 ppc4xx: Consolidate PPC4xx UIC defines
This patch is the first step to consolidate the UIC related defines in the
4xx headers. Move header from asm-ppc/ppc4xx-intvec.h to
asm-ppc/ppc4xx-uic.h as it will hold all UIC related defines in the next
steps.

36ea16f6a0 ppc4xx: Consolidate PPC4xx SDRAM/DDR/DDR2 defines, part1
This patch removes all SDRAM related defines from the PPC4xx headers
ppc405.h and ppc440.h. This is needed since now some 405 PPC's use
the same SDRAM controller as 440 systems do (like 405EX and 440SP).

It also introduces new defines for the equipped SDRAM controller based on
which PPC variant is used. There new defines are:

used on 405GR/CR/EP and some Xilinx Virtex boards.

used on 440GP/GX/EP/GR.

used on 440EPx/GRx.

used on 405EX/r/440SP/SPe/460EX/GT.

c821b5f120 ppc4xx: Enable Primordial Stack for 40x and Unify ECC Handling
This patch (Part 1 of 2):

* Rolls up a suite of changes to enable correct primordial stack and
  global data handling when the data cache is used for such a purpose
  for PPC40x-variants (i.e. CFG_INIT_DCACHE_CS).

* Related to the first, unifies DDR2 SDRAM and ECC initialization by
  eliminating redundant ECC initialization implementations and moving
  redundant SDRAM initialization out of board code into shared 4xx
  code.

* Enables MCSR visibility on the 405EX(r).

* Enables the use of the data cache for initial RAM on
  both AMCC's Kilauea and Makalu and removes a redundant
  CFG_POST_MEMORY flag from each board's CONFIG_POST value.

  - Removed, per Stefan Roese's request, defunct memory.c file for
    Makalu and rolled sdram_init from it into makalu.c.

With respect to the 4xx DDR initialization and ECC unification, there
is certainly more work that can and should be done (file renaming,
etc.). However, that can be handled at a later date on a second or
third pass. As it stands, this patch moves things forward in an
incremental yet positive way for those platforms that utilize this
code and the features associated with it.

087dfdb79b ppc4xx: Consolidate some of the 405 and 440 macros/structs into 4xx
This patch moves some common 4xx macros and the PPC405_SYS_INFO/
PPC440_SYS_INFO structure into the common ppc4xx.h header.

Lot's of other macros are good candidates to be consolidated this way
in the future.

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
