+       -----------------------------------------------------
+       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
