Actually, there was one recently.  The MTD_STUPID_LOCK flag was added,
and if the chip driver sets that for a particular chip the core will
unlock them when add_mtd_device is called.

You'd need to add a fixup to cfi_cmdset_0001.c for P30 to set that flag.
See the fixup_use_amtel_lock function in cfi_cmdset_0002.c for an
example.
