I _think_ you might be able to determine the size, no ? One way is to ask the vendor, but you can also try something like: 1) erase the whole SPI NOR 2) overwrite it with zeroes (or ones ? I think it should be all ones after erasing). 3) Erase sector 0 4) Read some 128 KiB back 5) Observe what is the difference.
