Why does it limit the FIFO to one byte only? The FIFO has 32 bytes. I would like to understand what problem you were trying to solve when you did the change: - if (!(readl(&uart->ts) & UTS_TXEMPTY)) + if (readl(&uart->ts) & UTS_TXFULL) Can you share a reproducer? We need to figure this out soon, as this is causing a regression.
