Because SUPPORT_15BITECC is defined, the following is dead code:
#elif SUPPORT_8BITECC
iowrite32(8, denali->flash_reg + ECC_CORRECTION);
#endif
Such ifdefs are useless and unacceptable coding style.
These writes are not needed in the first place since ECC_CORRECTION
is set up by the nand_init() function.
