Is this parameter actually used on these machines, or do we rely on the code in atapi_{input,output}_bytes:
#if defined(CONFIG_ATARI) || defined(CONFIG_Q40) if (MACH_IS_ATARI || MACH_IS_Q40) { /* Atari has a byte-swapped IDE interface */ insw_swapw(IDE_DATA_REG, buffer, bytecount / 2); return; } #endif /* CONFIG_ATARI */
and:
#if defined(CONFIG_ATARI) || defined(CONFIG_Q40) if (MACH_IS_ATARI || MACH_IS_Q40) { /* Atari has a byte-swapped IDE interface */ outsw_swapw(IDE_DATA_REG, buffer, bytecount / 2); return; } #endif /* CONFIG_ATARI */
