- Updated multiple RTL files in the and directories to include licensing information under the Mulan PSL v2.
- Added attribution comments for contributions from ETH Zurich and University of Bologna in .
- Enhanced test files in the directory with licensing details and ensured compliance with the Solderpad Hardware License, Version 0.51.
- Introduced a new test in to verify the preservation of attribution for PULP HyperBus sources.
- Updated test files to change instances of ribp_if to apb4_if in various test cases, ensuring consistency with the new APB4 interface.
- Modified assertions and checks in tests to reflect the new APB4 naming conventions, including changes in expected output and input files.
- Adjusted the test descriptions to accurately represent the APB4 functionality being tested, particularly in timer, UART, and GPIO tests.
- Ensured that all relevant paths and file names in the tests are updated to point to the new APB4 implementations, maintaining the integrity of the test suite.
- Updated formal.mk to include PSRAM in formal verification targets and source files.
- Modified software.mk to include psram_math.c for HAL.
- Enhanced pin_map.json to map GPIO pins for PSRAM control signals.
- Refactored ip_ribp_wrapper.sv to integrate PSRAM interface and remove unused ribp interfaces.
- Updated rtl_style_audit.json to include PSRAM related files.
- Added PSRAM testbench (psram_tb.sv) for integration testing.
- Created test_psram.py to validate PSRAM controller functionality and register offsets.
- Adjusted memory map tests to reflect new PSRAM address space and size.
