Subject: [PATCH] mtd: spi-nor: Add support for mx25r3235f
Add MTD support for the Macronix MX25R3235F SPI NOR chip from Macronix.
The chip has 4MB of total capacity, divided into a total of 64 sectors,
each 64KB sized. The chip also supports 4KB large sectors.
Additionally, it supports dual and quad read modes.
Functionality was verified on an HPE/Aruba AP-303 board.
