#4056 closed defect (fixed)

bsps/xilinx-zynq: Flush TX-Buffer before initializing the zynq-uart (cloned)

Description

Cloned from #4055:

We experienced that u-boot (at least from Xilinx repositories) does not wait until all its output has left the TX Buffer of the stdout uart, before handing over to the RTEMS application

This causes some garbage output at the begin of the RTEMS application in some cases and corrupts the test begin marker prohibiting rtems-test to recognize the test correctly.

Proposed fix is to let RTEMS wait until the TX Buffer of the uart is empty before configuring and using it.
