Davinci: NAND enable ECC even when not in NAND boot mode
Davinci: NAND enable ECC even when not in NAND boot mode
On Davinci platforms, the default NAND device is enabled (for ECC)
in low level boot code when NAND boot mode is used. If booting in
another mode, NAND ECC is not enabled. The driver should make
sure ECC is enabled regardless of boot mode if NAND is configured
in U-Boot.
