Due to an EOL the SPI flash on this product is changing. The old part is a Micron N25Q064A13ESE40F. Two new parts were qualified to reduce the impact of any potential EOL in the future. The new parts are the Microchip's SST26VF064BA, and ISSI's IS25LP064A.

Most applications will not be affected by this change unless they are manually accessing /dev/mtdblock0 or creating a custom U-Boot. In those cases some updates will be required.
