  1

  Modifications to support console multiplexing. This is controlled using
  CONFIG_SYS_CONSOLE_MUX in the board configuration file.

  This allows a user to specify multiple console devices in the environment
  with a command like this: setenv stdin serial,nc. As a result, the user can
  enter text on both the serial and netconsole interfaces.

  All devices - stdin, stdout and stderr - can be set in this manner.

  1) common/iomux.c and include/iomux.h contain the environment setting
  implementation.
  2) doc/README.iomux contains a somewhat more detailed description.
  3) The implementation in (1) is called from common/cmd_nvedit.c to
  handle setenv and from common/console.c to handle initialization of
  input/output devices at boot time.
  4) common/console.c also contains the code needed to poll multiple console
  devices for input and send output to all devices registered for output.
  5) include/common.h includes iomux.h and common/Makefile generates iomux.o
  when CONFIG_SYS_CONSOLE_MUX is set.
