With driver model this function does not work correctly and when CONFIG_DISPLAY_BOARDINFO_LATE is enabled we end up announcing U-Boot twice on the serial port. This causes the pytest framework to fail as it looks like a reset.
This series includes an interim patch to fix the test framework. However the correct fix is to avoid displaying the banner twice. This happens with driver model if the serial console device is not called "serial". Two patches enhance the check to use the uclass instead of the device name. This is a more reliable test.
We should not need to apply all three patches, but they are included in this series to allow the immediate test breakage to be fixed with a pytest change, while the other two patches are reviewed.
