[U-Boot-Users] NAND search for bad blocks on startup

[David Ashley]

The newer NAND system seems to do a bad block search on startup.
This takes several seconds when the NAND is big, like 256Mbytes.
How about an #ifndef around this search, like CFG_NAND_NO_BAD_BLOCK_SEARCH
so it can be turned off?

I can confirm the newer NAND system works with a 16 bit Micron NAND flash 
right out of the box once I've implemented the glue routines specific to my
board. Good job!

Before I knew about the newer git version and was modifying 1.1.4 I had
modified u-boot to support the micron NAND, but that work is irrelevant now.
Maybe u-boot is ready for a major new release 1.1.5???
