this change exposes checking the protection mechanism of SPI NOR flash chips to the CLI. it expands what was already there to communicate not only the protection state of a particular region, but also whether or not the hardware write protection mechanism of the chip is enabled.
the new command works for Micron (and compatible) SPI NOR flash chips as well as the SST26* series of SPI NOR flash chips.
the changes were tested on proprietary boards using a M25P16 and a SST26VF016B.
