commit 225bdb507cf199e746bec074df3ff7364f3f404d Author: Martin Roth martinroth@google.com Date: Mon Jan 23 14:56:55 2017 -0700
SeaBIOS Kconfig: Update logging
The SeaBIOS and coreboot log levels don't really align, so setting the SeaBIOS log level to the same as coreboot's isn't really what we want.
- Update default log level to use the default SeaBIOS log level. - Update the current help text to match the new defaults. - Add help text for what is displayed at various levels. - Get rid of separate type & prompt lines. - Add comments for default seabios level & logging disabled
