IIRC that "block protection" is implemented by the flash chip. If
opcode 0x50 succeeded, erase may work.

The problem is our prepared OPMENU does not contain 0x50. My idea is
to improve the opcode generating mechanism further. It may be better
to do lazy opcode programming and minimal opcode programming. That is,
do not program opcode at chipset initialization even when programming
is allowed. Only when we found a failed opcode, we try to modify one
opcode in OPMENU to the failed one, and then resend the opcode.
