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.
