This patch series consist of two ns16550-related patches. [PATCH v4 1/4] ns16550: support for UART with broken FIFO [PATCH v4 2/4] ns16550: make ns16550_serial_init_port() shorter [PATCH v4 3/4] ns16550: write zero to ier only once [PATCH v4 4/4] ns16550: fix ier selection The 1st one adds the flag (NS16650_FLAG_DISABLE_FIFO) in internal ns16550 data structure to recognise UART with broken FIFO (or UART without FIFO at all) and the code to use this flag. The flag can be set in board-related code. The 2nd one use the fact that ns16550_serial_init_port() and ns16550_setbaudrate() functions have many common code. It change the most of ns16550_serial_init_port() code for one ns16550_setbaudrate() call. The 3rd one removes unnecessary interrupt disable on every speed change operation. The 4th one adds explicit IER register selection before accessing it. _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
