- *  This file contains the MBX8xx termios serial I/O package.
- *  Only asynchronous I/O is supported.
- *
- *  The SCCs and SMCs are assigned as follows
- *
- *   Channel     Device      Minor   Note
- *    SMC1      /dev/tty0      0
- *    SMC2      /dev/tty1      1
- *    SCC1                     2     N/A. Hardwired as ethernet port
- *    SCC2      /dev/tty2      3
- *    SCC3      /dev/tty3      4
- *    SCC4      /dev/tty4      5
- *
- * The SCCs and SMCs on the eval board are assigned as follows
- *
- *   Channel     Device      Minor   Termios
- *    SMC1      /dev/tty3      4       no
- *    SMC2      /dev/tty4      5       no
- *    SCC1      /dev/tty0      0       no
- *    SCC2      /dev/console   1       yes
- *    SCC3      /dev/tty1      2       no  	* USED FOR NETWORK I/F
- *    SCC4      /dev/tty2      3       no	* USED FOR NETWORK I/F
- *
- *  All ports support termios. The use of termios is recommended for real-time
- *  applications. Termios provides buffering and input processing. When not
- *  using termios, processing is limited to the substitution of LF for CR on
- *  input, and the output of a CR following the output of a LF character.
- *  Note that the terminal should not send CR/LF pairs when the return key
- *  is pressed, and that output lines are terminated with LF/CR, not CR/LF
- *  (although that would be easy to change).
- *
- *  I/O may be interrupt-driven (recommended for real-time applications) or
- *  polled. Polled I/O may be performed by this device driver entirely, or
- *  in part by EPPCBug. With EPPCBug 1.1, polled I/O is limited to the
- *  EPPCBug debug console. This is a limitation of the firmware. Later
- *  firmware may be able to do I/O through any port. This code assumes
- *  that the EPPCBug console is the default: SMC1. If the console and
- *  printk ports are set to anything else with EPPCBug polled I/O, the
- *  system will hang. Only port SMC1 is usable with EPPCBug polled I/O.
- *
- *  LIMITATIONS:
- *
- *  It is not possible to use different I/O modes on the different ports. The
- *  exception is with printk. The printk port can use a different mode from
- *  the other ports. If this is done, it is important not to open the printk
- *  port from an RTEMS application.
- *
- *  Currently, the I/O modes are determined at build time. It would be much
- *  better to have the mode selected at boot time based on parameters in
- *  NVRAM.
- *
- *  Interrupt-driven I/O requires termios.
- *
- *  TESTS:
- *
- *  TO RUN THE TESTS, USE POLLED I/O WITHOUT TERMIOS SUPPORT. Some tests
- *  play with the interrupt masks and turn off I/O. Those tests will hang
- *  when interrupt-driven I/O is used. Other tests, such as cdtest, do I/O
- *  from the static constructors before the console is open. This test
- *  will not work with interrupt-driven I/O. Because of the buffering
- *  performed in termios, test output may not be in sequence.The tests
- *  should all be fixed to work with interrupt-driven I/O and to
- *  produce output in the expected sequence. Obviously, the termios test
- *  requires termios support in the driver.
- *
- *  Set CONSOLE_MINOR to the appropriate device minor number in the
- *  config file. This allows the RTEMS application console to be different
- *  from the EPPBug debug console or the GDB port.
- *
- *  This driver handles all five available serial ports: it distinguishes
- *  the sub-devices using minor device numbers. It is not possible to have
- *  other protocols running on the other ports when this driver is used as
- *  currently written.
