      serial/ns16550: add an option to avoid hanging on broken platforms · 7de0fe1a
      Javier Martinez Canillas authored
      Some platforms (e.g. IGEPv2 board) has a broken ns16550 UART that
      does not set the TEMT bit when the transmitter is empty in SPL.
      This makes U-Boot to hang while waiting for TEMT to be set.
      Add a new option to avoid this:
      16550 UART set the Transmitter Empty (TEMT) Bit when all output
      has finished and the transmitter is totally empty. U-Boot waits
      for this bit to be set to initialize the serial console. On some
      broken platforms this bit is not set in SPL making U-Boot to
      hang while waiting for TEMT. Define this option to avoid it.

      TEMT is set when the transmitter is totally empty and all output has
      This prevents output problems (including a loss of synchronization
      observed on p2020 that persisted for quite a while) if SPL has output
      still on its way out.

      serial: ns16550: Call usbtty_poll only in non-SPL build · f2041388
      Marek Vasut authored
      Having both USBTTY and CONFIG_SERIAL_MULTI enabled in SPL, the
      usbtty.c file is protected in Makefile to not be compiled into
      the SPL. Yet, the ns16550 serial driver does not contain such
      protection. Add it to avoid missing symbol error.

      ns16550: Add WATCHDOG_RESET to putc for short watchdog timeout boards · 1a2d9b30
      Stefan Roese authored and Wolfgang Denk's avatar Wolfgang Denk committed
      Call watchdog_reset() upon newline. This is done here in putc
      since the environment code uses a single puts() to print the complete
      envrironment upon "printenv". So we can't put this watchdog call
      in puts().
      This is needed for boards with a very short watchdog timeout, like the
      lwmon5 with a 100ms timeout. Without this patch this board resets in the
      commands with long outputs, like "printenv" or "fdt print".
      Note that the image size is not increased with this patch when
      CONFIG_HW_WATCHDOG or CONFIG_WATCHDOG are not defined since the compiler
      optimizes this additional code away.

      ZOOM2 Add serial support. · 660888b7
      Tom Rix authored and Wolfgang Denk's avatar Wolfgang Denk committed
      Zoom2 serial is in general supplied by one of the 4 UARTS on the debug board.
      The default serial is from the USB connector on left side of the debug board.
      The USB connector will produce 2 of the 4 UARTS.  On your host pick the first
      The details of the setting of the serial gpmc setup are not available.
      The values were provided by another party.
      The serial port set up is the same with Zoom1.

      Create configuration option for restricted ns16550 functions · f5675aa5
      Ron Madrid authored and Wolfgang Denk's avatar Wolfgang Denk committed
      This patch will create a configuration option for a minimum configuration for
      the ns16550 serial driver at drivers/serial/ns16550.c and will apply this new
      configuration option to the SIMPC8313.h config file in order to fix the NAND
      bootstrap build error.  This option will exclude all functions with exception of
      NS16550_putc and NS16550_init.  This will be used primarily to save space and
      remove unused code from builds in which space is limited.
