- Introduced for handling QSPI flash memory operations, including command and address handling. - Added to interface with the C++ flash memory implementation, allowing for read operations via DPI-C. - Created for the flash memory implementation, supporting initialization, reading, and memory copying. - Updated to integrate the new QSPI Flash module and connect it with the existing system. - Refactored file paths in various filelists and scripts to accommodate the new directory structure under . - Enhanced the Python scripts for generating memory maps and preparing the environment for the new structure. - Adjusted test scripts to reflect changes in the directory structure and ensure compatibility with the new modules.
