[U-Boot] [PATCH] NAND:Extending the nand_ecclayout structure

[U-Boot] [PATCH] NAND:Extending the nand_ecclayout structure

[s-paulraj at ti.com]

From: Sandeep Paulraj <s-paulraj@ti.com>

NANDs with page size of lesser than and equal to 2K are
reaching EOL. They are bing replaced with NANDs of
page size 4K and above.
To support this we have to extend the eccpos field

I believe a patch was submitted to linux-mtd to update this.
But this change was rejected to the best of my knowledge because
it will break user space IOCTL's, i.e. when we we run some tests
from the mtd-utils. I can't see an solution to the issue addressed
in the kernel or mtd-utils. I think this can be added to u-boot.
