+       help
+         This option allows the console to be silenced, meaning that no
+         output will appear on the console devices. This is controlled by
+         setting the environment vaariable 'silent' to a non-empty value.
+         Note this also silences the console when booting Linux.
+
+         When the console is set up, the variable is checked, and the
+         GD_FLG_SILENT flag is set. Changing the environment variable later
+         will update the flag.

+         Normally when the U-Boot console is silenced, Linux's console is
+         also silenced (assuming the board boots into Linux). This option
+         allows the linux console to operate normally, even if U-Boot's

+         When the 'silent' environment variable is changed, update the
