Since there is no context here, I cannot really comment, but is this
about SPI NOR being in 4-byte addressing mode and bootrom which does
not support it? If so, what happens if you press reset button on the
device ? SPI NOR remains in undefined mode and bootrom won't read the
bootloader from it. The only real fix is to implement CORRECT dedicated
SPI NOR reset logic.
