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

+ - SPL boot does not support reading of ONFI parameters. This is done to
+ keep SPL code foot-print small.
+ - In current U-Boot flow using nand_init(), driver initialization

+ (nand_scan_ident + nand_scan_tail), thus device's ONFI parameters are
+ not available while configuring controller. So a static CONFIG_NAND_xx
+ is needed to know the device's bus-width in advance.
+ Some drivers using above config are:

+
+ 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.
