Product:
 
- u-boot
 
Version:
 
- 1.0.0-pre
 
CHANGELOG:
 
- Adding is_console_quiet() to support runtime changes in console output
 
CVS Comments:
 
- Adding the CFG_CONSOLE_IS_QUIET option to support runtime changes in
  console output.  The is_console_quiet() function is used to
  determine the status of quiet mode.  Quiet mode is based on the
  value of the "quiet" environment variable.  Non-zero values indicate
  that quiet mode is active.
