### Is your feature request related to a problem? Please describe. Currently, the PL011 UART driver is not very flexible. All boards that use it must use the common Kconfig options which limit you to 3 UART interfaces. All code is handled within the driver, and expects that each UART interface has its own unique interrupt. This does not apply to the Pi4B, which has 5 PL011 UART interfaces and they all share one common interrupt handler. In order to use the PL011 driver with the Pi4B, this driver needs to be modified. ### Describe the solution you'd like Modify the PL011 UART driver so that individual boards can use the C API to: - Register as many UARTs as they need - Control interrupt registration - Define their own Kconfig options for selecting active UART interfaces/options ### Describe alternatives you've considered _No response_ ### Verification - [x] I have verified before submitting the report. -- This is an automated message from the Apache Git Service.
