* Patch by Richard Woodruff, 24 Jul 2003:
Fixes for cmd_nand.c:
- Fixed null dereferece which could result in incorrect ECC values.
- Added support for devices with no Ready/Busy signal hooked up.
- Added OMAP1510 read/write protect handling.
- Fixed nand.h's ECCPOS. A conflict existed with POS5 and badblock
for non-JFFS2.
- Switched default ECC to be JFFS2.
