da01f53404 mpc512x: fix fixed_sdram() init code.
Commit 054197ba and later fixes used an array to initialize some of
the MDDRC parameters; however, the use of an array turned out to be a
bad idea as it was not possible to correlate structure entries to
array indices in readable and reliable way. Now we use a struct
instead, which makes this self-explanatory.

054197ba8e mpc512x: Streamlined fixed_sdram() init sequence.
Signed-off-by: Martha M Stan <mmarx@silicontkx.com>

Minor cleanup:

Re-ordered default_mddrc_config[] to have matching indices.

This allows to use the same index "N" for source and target fields;
before, we had code like this

	out_be32(&im->mddrc.ddr_time_config2, mddrc_config[3]);

which always looked like a copy & paste error because 2 != 3.

Also, use NULL when meaning a null pointer.

3b74e7ec58 MPC512x: remove include/mpc512x.h
Move needed definitions (register descriptions etc.) from
include/mpc512x.h  into  include/asm-ppc/immap_512x.h.

Instead of using a #define'd register offset, use a function that
provides the PATA controller's base address.

All the rest of include/mpc512x.h are register offset definitions
which can be eliminated by proper use of C structures.

There are only a few register offsets remaining that are needed in
cpu/mpc512x/start.S; for these we provide cpu/mpc512x/asm-offsets.h
which is intended as a temporary workaround only. In a later patch
this file will be removed, too, and then auto-generated from the
respective C structs.

abfbd0ae49 ADS5121 Add IC Ident Module (IIM) support
IIM (IC Identification Module) is the fusebox for the mpc5121.
Use #define CONFIG_IIM to turn on the clock for this module
use #define CONFIG_CMD_FUSE to add fusebox commands.
Fusebox commands include the ability to read
the status, read the register cache, override the register cache,
program the fuses and sense them.

5f91db7f58 MPC5121e ADS PCI support take 3
Adds PCI support for MPC5121

Tested with drivers/net/rtl8139.c

Support is conditional since PCI on old silicon does not work.

ads5121_PCI_config turns on PCI

In this version, condition compilation of PCI code has been moved
from ifdef in board/ads5121/pci.c to board/ads5121/Makefile as
suggested by Jean-Christophe PLAGNIOL-VILLARD
