The silent console as currently implemented is not silent if a board has been newly manufactured. I.e., some messages are printed prior to being able to set the "silent" environment variable the first time.
The following patch adds a new configuration option, CONFIG_VERY_SILENT_CONSOLE, which modifies the behavior slightly. If this option is selected, then the absence of the "silent" variable will result in a default behavior of "silent". Also, if "silent" is set to "1", then the behavior will be "silent". Only if a different value, say "0", is selected will the behavior be "verbose".
This patch doesn't change the behavior for any existing BSP's because they will not have selected the CONFIG_VERY_SILENT_CONSOLE option.
