Precautions
===========
In the new version of QEMU (9.20), the UART RX interrupt and TX interrupt have been swapped.
Adjustments need to be made using menuconfig::
CONFIG_CMSDK_UART0_TX_IRQ=50
CONFIG_CMSDK_UART0_RX_IRQ=49
For details, see `fix RX/TX interrupts order <https://github.com/qemu/qemu/commit/5a558be93ad628e5bed6e0ee062870f49251725c>`_
