This series adds a QEMU model for the K230 SoC DesignWare 8250-compatible UART controller, wires it into the K230 SoC, and adds qtest coverage.
The implementation supports the registers and features required by the Linux 8250_dw driver, providing an interactive shell over the serial port. Changes since v1 [1]: - Split into a 3-patch series. - Fixed indentation of preprocessing macros. Testing: 8 qtest cases pass. With the k230-boot-assets image from https://github.com/zevorn/k230-boot-assets, the driver probes successfully and the shell works bidirectionally over pty.
