Historically the 405 U-Boot port had a dram_init() call in early init
stage. This function was still called from start.S and most of the time
coded in assembler. This is not needed anymore (since a long time) and
boards should implement the common initdram() function in C instead.
This patch now removed the dram_init() call from start.S and removes the
empty implementations that are scattered through most of the 405 board
ports. Some older board ports really implement this dram_init() though.
These are:
csb272
csb472
ERIC
EXBITGEN
W7OLMC
W7OLMG
I changed those boards to call this assembler dram_init() function now
from their board specific initdram() instead. This *should* work, but please
test again on those platforms. And it is perhaps a good idea that those
boards use some common 405 SDRAM initialization code from cpu/ppc4xx at
some time. So further patches welcome here.

Since the current dflush() implementation is know to have some problems
(as seem on lwmon5 ECC init) this patch removes it completely and replaces
it by using clean_dcache_range().
Tested on Katmai with ECC DIMM.

This patch changes the physical addess parameter from 32bit to 64bit.
This is needed for 36bit 4xx platforms to access areas located
beyond the 4GB border, like SoC peripherals (EBC etc.).

- Moved some common code to nestal/common/nm_bsp.c.
- Added support for the vxWorks EDR.
- Enable trace for Lauterbach, if present.
- Added support for POST.
- Stylistic cleanups (multi-line comments/ enforce 80 colomn width)

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.

platforms wishing to display RAM diagnostics in addition to size,
can do so, on one line, in their own board_add_ram_info()
implementation.
this consequently eliminates CONFIG_ADD_RAM_INFO.
Thanks to Stefan for the hint.

Make ecc initialisation robust, as DDR2-ECC errors may be generated
while zeroing the RAM.
Return 16 bytes (a cacheline) less than the available memory, as the
board and/or PPC440EPx might have problems accessing the last bytes.
