I think this will apply for chip 0 and 1. It should be rather easy to actually make it chip 0/1 compatible, just check for i as it is done above with chip_[0|1]_device_path, e.g.

if (i == 0 && md->cfg.chip_0_size)
    miu->size = md->cfg.chip_0_size;
else if (i == 1 && md->cfg.chip_1_size)
    miu->size = md->cfg.chip_1_size;

/* verify it's a nand */
if (miu->type != MTD_NANDFLASH
&& miu->type != MTD_MLCNANDFLASH) {
