Fabio and Pali,
Seems reasonable but this does not resolve the problem. Whatever I print in board_init gets cutoff by the print from dm_announce.
Should we check for both TXFULL and TXEMPTY conditions?

- if (readl(&uart->ts) & UTS_TXFULL) + if ((readl(&uart->ts) & UTS_TXFULL) || !(readl(&uart->ts) & UTS_TXEMPTY))
This may bring the issue that Johannes met back
