[U-Boot] NAND UnCorrectable RS-ECC Error on Freescale MXC

[alfred steele]

Hi  All,

I am trying to introduce  a Samsung NAND flash part (K9F8G08U0M) to a
Freescale mxc platform. Looks like the device code used in the NAND
"read id" operation is already a part of  the
drivers/mtd/nand/nand_ids.c, looking at line "{"NAND 1GiB 3,3V 8-bit",
   0xD3, 0, 1024, 0, LP_OPTIONS},) Its different in the sense that it
has a page size of 4K but the code specific to 4k page size handling
seems to be there in the code

After booting out of RAM, i am getting  "UnCorrectable RS-ECC Error"
during an initial page read operation.
