mpc83xx: clean up cache operations and unlock_ram_in_cache() functions
Cleans up some latent issues with the data cache control so that
dcache_enable() and dcache_disable() will work reliably (after
unlock_ram_in_cache() has been called)

mpc83xx: Store and display Arbiter Event Register values
Record the Arbiter Event Register values and optionally display them.
The Arbiter Event Register can record the type and effective address of
an arbiter error, even through an HRESET. This patch stores the values in
the global data structure.
Display of the Arbiter Event registers immediately after the RSR value
can be enabled with defines. The Arbiter values will only be displayed
if an arbiter event has occured since the last Power On Reset, and either
of the following defines exist:
#define CONFIG_DISPLAY_AER_BRIEF - display only the arbiter address and
and type register values
#define CONFIG_DISPLAY_AER_FULL - display and interpret the arbiter
event register values
Address Only transactions are one of the trapped events that can register
as an arbiter event. They occur with some cache manipulation instructions
if the HID0_ABE (Address Broadcast Enable) is set and the memory region
has the MEMORY_COHERENCE WIMG bit set. Setting:
#define CONFIG_MASK_AER_AO - prevents the arbiter from recording address
only events, so that it can still capture
other real problems.

MPC83XX: Fix GPIO configuration - set gpio level before direction
Set DAT value before DIR values to avoid creating glitches on the
GPIO signals.
Set gpio level register before direction register to inhibit
glitches on high level output pins.
Dir and data gets cleared at powerup, so high level output lines see
a short low pulse between setting the direction and level registers.
Issue was seen on a new board with the nReset line of the NOR flash
connected to a GPIO. Setting the direction register puts the NOR flash
in reset so the next instruction to set the level cannot get executed.

AP325RXA is SH7723's reference board.
This has SCIF, NOR Flash, Ethernet, USB host, LCDC, SD Host, Camera and other.
In this patch, support SCIF, NOR Flash, and Ethernet.
SMDK6400 can only boot U-Boot from NAND-flash. This patch adds a nand_spl
driver for it too. The board can also boot from the NOR flash, but due to
hardware limitations it can only address 64KiB on it, which is not enough
for U-Boot. Based on the original sources by Samsung for U-Boot 1.1.6.
Notice: USB on S3C6400 currently works _only_ with switched off MMU. One could
try to enable the MMU, but map addresses 1-to-1, and disable data cache, then
it should work too and we could still profit from instruction cache.

ARM DaVinci: Changing function names for EMAC driver
DM644x is just one of a series of DaVinci chips that use the EMAC driver.
By replacing all the function names that start with dm644x_* to davinci_*
we make these function more portable. I have tested this change on my EVM.
DM6467 is another DaVinci SOC which uses the EMAC driver and i will
be sending patches that add DaVinci DM6467 support to the list soon.
- memsetup.s is changed/merged to lowlevel_init.S
memsetup.S has a global label memsetup that just returns back to caller
- memsetup global label is changed/merged to lowlevel_init
This label is not called from anywhere.

dm9000 has code to detect and initialize external phy parts, but later

change the GPIO initialization so that only the GPIO used as an
