[U-Boot] Uboot support for MT29F2G16ABBEAH4 NAND 16 bit

[marcio at netopen.com.br]

Hi 

has Anybody managed to load the Linux Kernel using MT29F2G16ABBEAH4 NAND or
other 16 bits NAND memory?

Thanks
Marcio

I haven't personally, but there's no general reason why 16-bit NAND  
shouldn't work in U-Boot.  Some NAND controllers or drivers don't  
support it, though -- which controller are you using?

Hi Scott 

Thanks a lot for your attention. 

I am using a custom
board based at the Atmel AT91SAM9M10G45-EK Development Kit. I am quite
sure The Linux Kernel is properly loaded in the NAND memory. 

Here is
