+	Above config is useful when NAND device's bus-width information cannot

+	How to select ECC scheme on OMAP and AMxx platforms ?
+	-----------------------------------------------------
+	Though higher ECC schemes have more capability to detect and correct
+	bit-flips, but still selection of ECC scheme is dependent on following
+	- hardware engines present in SoC.
+		Some legacy OMAP SoC do not have ELM h/w engine thus such
+		SoC cannot support BCHx_HW ECC schemes.
+	- size of OOB/Spare region
+		With higher ECC schemes, more OOB/Spare area is required to
+		store ECC. So choice of ECC scheme is limited by NAND oobsize.
+
+	In general following expression can help:
+		NAND_OOBSIZE >= 2 + (NAND_PAGESIZE / 512) * ECC_BYTES
+	where
+		NAND_OOBSIZE	= number of bytes available in
+				OOB/spare area per NAND page.
+		NAND_PAGESIZE	= bytes in main-area of NAND page.
+		ECC_BYTES	= number of ECC bytes generated to
+				protect 512 bytes of data, which is:
+				3 for HAM1_xx ecc schemes
+				7 for BCH4_xx ecc schemes
+				14 for BCH8_xx ecc schemes
+				26 for BCH16_xx ecc schemes
+
+		example to check for BCH16 on 2K page NAND
+		NAND_PAGESIZE = 2048
+		NAND_OOBSIZE = 64
+		2 + (2048 / 512) * 26 = 106 > NAND_OOBSIZE
+		Thus BCH16 cannot be supported on 2K page NAND.
+
+		However, for 4K pagesize NAND
+		NAND_PAGESIZE = 4096
+		NAND_OOBSIZE = 64
+		ECC_BYTES = 26
+		2 + (4096 / 512) * 26 = 210 < NAND_OOBSIZE
+		Thus BCH16 can be supported on 4K page NAND.
