Pull request overview
This PR adds two new common MTD (Memory Technology Device) drivers for RT-Thread's Device Manager (DM) framework: a CFI-compliant NOR flash driver and an SPI NOR flash driver. These drivers provide standardized interfaces for flash memory devices commonly found in embedded systems, targeting QEMU, Raspberry Pi 3/4, and Rockchip 3500 platforms.
Key Changes:
- Added CFI (Common Flash Interface) NOR flash driver with comprehensive support for Intel and AMD command sets
- Added SPI NOR flash driver leveraging SFUD (Serial Flash Universal Driver) framework
- Updated build configuration to conditionally compile new drivers based on Kconfig options
