This patch adds the CONFIG_4xx_DCACHE options to some SDRAM init files
and to the Sequoia TLB init code. Now the cache can be enabled on 44x
boards by defining CONFIG_4xx_DCACHE in the board config file. This
option will disappear, when more boards use is successfully and no
more known problems exist.
This is tested successfully on Sequoia and Katmai. The only problem that
needs to be fixed is, that USB is not working on Sequoia right now, since
it will need some cache handling code too, similar to the 4xx EMAC driver.

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.

Changed storage type of cfg_simulate_spd_eeprom to const
Changed storage type of gpio_tab to stack storage
(Cannot access global data declarations in .bss until afer code relocation)
Improved SDRAM tests to catch problems where data is not uniquely addressable
(e.g. incorrectly programmed SDRAM row or columns)
Added CONFIG_PROG_SDRAM_TLB to support Bamboo SIMM/DIMM modules
Fixed AM29LV320DT (OpCode Flash) sector map

- Show on the Status LEDs, some States of the board.
- Get the MAC addresses from the EEProm
- use PREBOOT
- use the CF on the board.
- check the U-Boot image in the Flash with a SHA1
checksum.
- use dynamic TLB entries generation for the SDRAM

Now program_tlb() allows to program a TLB (or multiple) with
different virtual and physical addresses. With this change, now one
physical region (e.g. SDRAM) can be mapped 2 times, once with caches
diabled and once with caches enabled.

This patch fixes a problem that occurs when 2 DIMM's are
used. This problem was first spotted and fixed by Gerald Jackson
<gerald.jackson@reaonixsecurity.com> but this patch fixes the
problem in a little more clever way.
This patch also adds the nice functionality to dynamically
create the TLB entries for the SDRAM (tlb.c). So we should
never run into such problems with wrong (too short) TLB
initialization again on these platforms.
As this feature is new to the "old" 44x SPD DDR driver, it
has to be enabled via the CONFIG_PROG_SDRAM_TLB define.

Since the existing 4xx SPD SDRAM initialization routines for the
405 SDRAM controller and the 440 DDR controller don't have much in
common this patch splits both drivers into different files.
This is in preparation for the 440 DDR2 controller support (440SP/e).

AMCC suggested to set the PMU bit to 0 for best performace on
the PPC440 DDR controller.
Please see doc/README.440-DDR-performance for details.
