* Patches by Denis Peter, 9 Sep 2003:
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.
