x86 update
* Patch by Dave Ellis, 9 May 2003 + 27 May 2003:
add nand flash support to SXNI855T configuration
fix/extend nand flash support:
- fix 'nand erase' command so does not erase bad blocks
- fix 'nand write' command so does not write to bad blocks
- fix nand_probe() so handles no flash detected properly
- add doc/README.nand
- add .jffs2 and .oob options to nand read/write
- add 'nand bad' command to list bad blocks
- add 'clean' option to 'nand erase' to write JFFS2 clean markers
- make NAND read/write faster
