Description

InputClockHz for uart seems to be hardcoded before setting proper configuration for baudrate in e.g.:

Research direction

Start with lib/bsp/standalone/src/arm/cortexa53/32bit/uart.c at the referenced line and trace how InputClockHz is used before baud-rate configuration. Confirm the intended clock source and update the configuration so the UART no longer relies on a hardcoded 25 MHz value; verify baud-rate setup across the affected path.
