Constantly reinitializing the Cadence UART on every character output causes data corruption/loss on some ZynqMP hardware. Only initialize the UART once for early output and give it a kick on startup.
This is the serial controller portion of the libchip library. This directory contains the source code for reusable console driver support code. Each individual driver is configured using the console_tbl data structure. This structure is defined and explained in the console.h file. The reusable chip drivers do not directly access the serial controller. They access the registers on the controller via a set of up to four functions which are provided by the BSP. These functins set and get general registers and data buffers. Some chips can access the data buffers as general registers and thus the driver may not require those interface routines.
