The following changes were made to sync up the DMA code between the 85xx
and 86xx architectures which will make it easier to break out common
8xxx DMA code:
85xx:
- Don't set STRANSINT and SPCIORDER fields in SATR register. These bits
only have an affect when the SBPATMU bit is set.
- Write 0xffffffff instead of 0xfffffff to clear errors in the DMA
status register. We may as well clear all 32 bits of the register...
86xx:
- Add CONFIG_SYS_MPC86xx_DMA_ADDR define to address DMA registers
- Add clearing of errors in the DMA status register when initializing
the controller
- Clear the channel start bit in the DMA mode register after a transfer

The uec driver contains code to hard code configuration information for the uec
ethernet controllers. This patch creates an array of uec_info structures, which
are then parsed by the corresponding driver instance to determine configuration.
It also creates function uec_standard_init() to initialize all UEC interfaces
for 83xx and 85xx.

Its reasonable that we may have ethernet devices but dont have drivers
or support enabled for them in u-boot and want the device tree fixed up.
Unconditionally calling the ethernet fixup is fine since if we dont have
ethernet nodes that match (or aliases) we will not attempt to do
anything.

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.

Many of the help messages were not really helpful; for example, many
commands that take no arguments would not print a correct synopsis
line, but "No additional help available." which is not exactly wrong,
but not helpful either.
Commit ``Make "usage" messages more helpful.'' changed this
partially. But it also became clear that lots of "Usage" and "Help"
messages (fields "usage" and "help" in struct cmd_tbl_s respective)
were actually redundant.
This patch cleans this up - for example:
Before:
=> help dtt
dtt - Digital Thermometer and Thermostat
Usage:
dtt - Read temperature from digital thermometer and thermostat.
After:
=> help dtt
dtt - Read temperature from Digital Thermometer and Thermostat
Usage:
dtt

Add some basic declarations for DaVinci DM355/DM350/DM335 support,
keyed on CONFIG_SOC_DM355. (DM35X isn't quite right because the
DM357 is very different; while the DM355 is like a DM355 without
the MPEG/JPEG coprocessor).
These have different peripherals than the DM6446, and some of
the peripherals are at different addresses. Notably for U-Boot,
there's no EMAC, and the NAND controller address is different

Split out DaVinci DM6446-specific bits from more generic bits:
- Add a CONFIG_SOC_DM644X. All current boards use DM6446 chips;
DM6443 and DM6441 chips differ in available peripherals.
- Move most DM644X-specific bits from psc.c to a new dm644x.c file,
which is conditionally built. It provides device-specific setup.
Plus minor coding style and comment updates with respect to the PSC.
