Hi Bin Meng, Thanks for the detailed review. Regarding the suggestion to abstract this into a generic Synopsys DesignWare APB GPIO model, I have a question: do you know of any other QEMU SoCs that use this IP and would benefit from a shared model? If there is no immediate second user, I wonder whether it might be premature to generalize now, especially while we still need to complete the K230-specific behavior. Thanks, Junze Cao
