16-bit NAND support

Hi,

This is a patch to add 16-bit NAND support to u-boot. It doesn't change any existing 8-bit NAND code so it shouldn't affect any existing boards that have 8-bit chips. I tested it in 2 TI OMAP boards, one using software to access chip, the other one using hardware NAND controller.

Regards,
Jian

Did you actually _check_ if it has impact on exiting boards? Impact on parameters like code size, for example?

I have applied ur patch to my u-boot1.1.1 code and one error is
generated.The log is shown below.can any one please tell me what can be the problem.And also pls tell me how do I select that whether I m going to use 8bit Nand flash or 16bit Nand flash.Is there any CONFIG variable is required to define.I m working on a 16bit Nand flash from the Samsung.

Please use current code (top of CVS).

Added, thanks.

Please don't forget the CHANGELOG entry, and _please_ stick to the Coding Style!
