Pull Request Overview
This PR adds SPI NAND Flash driver support by introducing a comprehensive driver implementation with optional software ECC support using BCH (Bose-Chaudhuri-Hocquenghem) error correction algorithms.
- Complete SPI NAND flash driver with read, write, and erase operations
- Optional software-based ECC support with BCH algorithm implementation
- Device tree binding and configuration support for SPI NAND devices
