SPI Flash block device

SPIFBlockDevice class hierarchy

This API is a block device for NOR-based SPI flash devices that support SFDP.

Note: Multiple protocols exist for SPI flash devices. This driver is for the SFDP SPI flash protocol. If your device uses the DataFlash protocol, you need the DataflashBlockDevice

NOR-based SPI flash supports byte-sized read and writes, with an erase size of around 4 kbytes. An erase sets a block to all 1s, with successive writes clearing set bits.

To configure this class, please see our BlockDevice configuration documentation.
