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 = 224
|
|
|
|
|
ECC_BYTES = 26
|
|
|
|
|
2 + (4096 / 512) * 26 = 210 < NAND_OOBSIZE
|
|
|
|
|
Thus BCH16 can be supported on 4K page NAND.

Indicates that NAND device has 16-bit wide data-bus. In absence of this
|
|
|
|
|
config, bus-width of NAND device is assumed to be either 8-bit and later
|
|
|
|
|
determined by reading ONFI params.
|
|
|
|
|
Above config is useful when NAND device's bus-width information cannot
|
|
|
|
|
be determined from on-chip ONFI params, like in following scenarios:
|
|
|
|
|
- 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
|
|
|
|
|
happens in board_nand_init() which is called before any device probe
|
|
|
|
|
(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.
