- Added i2c_if.sv and spi_if.sv to rtl_style_audit.json for proper inclusion in style checks. - Updated test_i2c.py to reference i2c_if.sv from the serial directory instead of the cluster IP directory. - Modified test_spisd.py to point to spi_if.sv in the storage directory instead of the cluster IP directory.

Third-party attribution
This repository contains RTL source files that retain copyright and attribution information from third-party open-source projects in their original file headers. The following projects are explicitly referenced in the RTL sources currently present in this repository.
1. ETH Zurich and University of Bologna
Several RTL files retain the original copyright notice from ETH Zurich and University of Bologna, including files under the following paths:
- rtl/managed/clusterip/**
- rtl/managed/mpw/core/username7/ibex/**
- rtl/tech/tc_clk.sv
The header in rtl/tech/tc_clk.sv also states the Solderpad Hardware License, Version 0.51.
2. Ravenna / PicoRV32 in ASIC
The following RTL files retain the original header from the Ravenna example SoC project, which refers to a design using PicoRV32 in ASIC:
- rtl/ip/peripheral/gpio.sv
- rtl/ip/peripheral/timer.sv
- rtl/ip/serial/uart.sv
The preserved notice attributes the work to Clifford Wolf and Tim Edwards.
3. Hirosh Dabui
The SDRAM controller implementation in rtl/ip/memory/sdram_core.sv retains the original copyright notice attributed to Hirosh Dabui.
4. EmbedFire
Several SPI SD card related RTL files retain the original attribution to EmbedFire and refer to source files such as sd_init.v, sd_write.v, sd_read.v, and data_rw_ctrl.v:
- rtl/ip/storage/spisd_core.sv
- rtl/ip/storage/spisd_data.sv
- rtl/ip/storage/spisd_init.sv
- rtl/ip/storage/spisd_read.sv
- rtl/ip/storage/spisd_write.sv
These headers state that the original code was published on GitHub by EmbedFire, but that the original license was not specified in the retained header.
5. Device simulation models
The simulation-only models under rtl/model/ retain their upstream notices
and source formatting. The AT24 model is imported from the retroSoC I2C
repository, the microphone model from the retroSoC I2S repository, and the
W25Q128JVxIM model from the retroSoC SPI repository. The Winbond model retains
its original Winbond Electronics Corporation copyright and "All Rights
Reserved" notice; its inclusion does not relicense it under Mulan PSL v2.
