EXTENDED_ID_NAND("NAND 256MiB 1,8V 16-bit", 0xBA, 256, LP_OPTIONS16),
Seems already supported by the NAND core. The MTD way of probing
a non-ONFI device is by using the IDs in nand_ids.c. Additional
configuration (timings in this case) is applied between the nand_scan_ident()
and nand_scan_tail() calls.
