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.
