* Patch by Scott McNutt, 21 Jul 2003:
Add support for LynuxWorks Kernel Downloadable Images (KDIs). Both LynxOS and BlueCat linux KDIs are supported. * Patch by Richard Woodruff, 25 Jul 2003: use more reliable reset for OMAP/925T * Patch by Nye Liu, 25 Jul 2003: fix typo in mpc8xx.h * 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.
