* hw/char/stm32l4x5_usart: Fix memory corruption by adding correct class_sizeThomas Huth2024-04-301-0/+1
| | | | | | | | | | | | | "make check-qtest-aarch64" recently started failing on FreeBSD builds, and valgrind on Linux also detected that there is something fishy with the new stm32l4x5-usart: The code forgot to set the correct class_size here, so the various class_init functions in this file wrote beyond the allocated buffer when setting the subc->type field.

* hw/char/stm32l4x5_usart: Enable serial read and writeArnaud Minier2024-04-251-0/+143
| | | | | | | | | | | | | | | Implement the ability to read and write characters to the usart using the serial port. The character transmission is based on the cmsdk-apb-uart implementation.

* hw/char: Implement STM32L4x5 USART skeletonArnaud Minier2024-04-251-0/+396
Add the basic infrastructure (register read/write, type...) to implement the STM32L4x5 USART. Also create different types for the USART, UART and LPUART of the STM32L4x5 to deduplicate code and enable the implementation of different behaviors depending on the type.
