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.

add FAT support for IDE, SCSI and USB
* Patches by Gleb Natapov, 2 Sep 2003:
- cleanup of POST code for unsupported architectures
- MPC824x locks way0 of data cache for use as initial RAM;
this patch unlocks it after relocation to RAM and invalidates
the locked entries.
* Patch by Gleb Natapov, 30 Aug 2003:
new I2C driver for mpc107 bridge. Now works from flash.
* Patch by Dave Ellis, 11 Aug 2003:
- JFFS2: fix typo in common/cmd_jffs2.c
- JFFS2: fix CFG_JFFS2_SORT_FRAGMENTS option
- JFFS2: remove node version 0 warning
- JFFS2: accept JFFS2 PADDING nodes
- SXNI855T: add AM29LV800 support
- SXNI855T: move environment from EEPROM to flash
- SXNI855T: boot from JFFS2 in NOR or NAND flash
* Patch by Bill Hargen, 11 Aug 2003:
fixes for I2C on MPC8240
- fix i2c_write routine
- fix iprobe command
- eliminates use of global variables, plus dead code, cleanup.

- remove trailing white space, trailing empty lines, C++ comments, etc.
- split cmd_boot.c (separate cmd_bdinfo.c and cmd_load.c)
* Patches by Kenneth Johansson, 25 Jun 2003:
- major rework of command structure
(work done mostly by Michal Cendrowski and Joakim Kristiansen)
