For all flash with non-volatile status register the WP pin is irrelevant
from reset until software (in same write-enabled flash) writes block
protection into the status register. (Only then does the WP pin matter.)

The later that status register write happens the more time there
is for anything with access to the SPI bus to write to the flash.
