[U-Boot] NAND Flash with Internal Hardware ECC

[Rajiv Dave]

Hi,

We are using an Atmel AT91SAM9263 processor which supports 1 Bit ECC flash
devices that have Block 0 Valid with no ECC. These devices are now obsolete.

We have fitted a board with a MT29F2G08ABAEWP-E-E, which has an internal
Hardware ECC engine. Would you know how provide support for this device
within U-Boot?

The following output is generated by a board fitted with the NAND Flash with
Internal Hardware ECC
