This repo contains:

• embeddded-nand: An attempt to create a NAND equialent of the NOR traits in embedded-storage. Probably a bit more complicated than required at the moment. Contains helpers for converting between byte addresses, block addresses and page addresses and for iterating over blocks and pages.
• embedded-nand-async: Async version of the above
• spi-nand: A generic driver for SPI NAND flash chips. Implements the embedded-nand and embedded-nand-async traits. Adding support for most devices should be trivial
• spi-nand-devices: Device support crate that enables the used of the spi-nand device type for specific devices. Currently supports the winbond W25N range. Also supports device specific features outside the scope of the generic spi-nand device.
• flashmap: A simple read focussed flash translation layer that targets the embedded-nand and embedded-nand-async traits. Maps logical blocks to physical blocks, remapping bad blocks when a read/write/erase fails.
