Note that in case of OpenWrt, there if 481-mtd-spi-nor-rework-broken-flash-reset-support.patch, which causes the flash to restore to 3 byte addressing after each operation. > This implementation makes it only break when a kernel panic happens during > flash operation on 16M+ areas. So it should be "good-enough" for most use-cases.
