[U-Boot] Support for NANDs greater than/equal to 4 GB

Scott,

There was a patch some time which added the 64 bit support in the MTD subsystem. I am referring to the patch below

http://git.infradead.org/mtd-2.6.git/blobdiff/8a4c2495b142fe612b291a810d9e69...

This feature still is not part of U-Boot. Is it going to be added?

Without this NANDs of size greater than equal to 4 GB fail to get recognized.

Thanks, Sandeep
