i.MX6S/GPMI-NAND issue on 3.5.4

Hello,

I'm facing some issue with GPMI-NAND driver on i.MX6 solo.
I've a TOSHIBA 4KiB page NAND connected to the GPMI.
(4KiB + 128 bytes OOB)

I tested it using the following,

1) U-boot v2012.04
2) Freescale's U-boot for i.MX6
3) Freescale's Kernel 3.0.15
	Result: 0x98 0xAC 0x90 0x26 (Correct)

4) Linux v3.5.4 stable
	Result: 0x98 0xA8 0x90 0x20 (Incorrect)

When I issue a READID command, 1, 2 & 3 gives me correct results, 
whereas the 3.5.4 version gives me some different result.

Any help would be very much appreciated.

Regards,
Vikram
