This option has never had much if any use. It solved a problem over 10 years ago that resulted from an argument over the value or lack thereof of including all the debug strings in a coreboot image. The answer is in: it's a good idea to maintain the capability to print all messages, for many reasons. This option is also misleading people, as in a recent discussion, to believe that log messges are controlled at build time in a way they are not. For the record, from this day forward, we can print messages at all log levels and the default log level is set at boot time, as directed by DEFAULT_CONSOLE_LOGLEVEL. You can set the default to 0 at build time and if you are having trouble override it in CMOS and get more messages. Besides, a quick glance shows it's always set to max (9 in this case) in the very few cases (1) in which it is set. Change-Id: I60c4cdaf4dcd318b841a6d6c70546417c5626f21 Signed-off-by: Ronald G.
