-General information on boot logs
-================================
-To gather good boot logs, you must set the debug level to Spew.
-
-If your board uses CMOS configuration[1], you can do it like this:
-nvramtool -w debug_level=Spew
-
-Else you will need to have to set the default log level at compile
-time, to do that go in "Console  --->" in make menuconfig, then set
-"Default console log level" to SPEW
-
-Reference:
-----------
-[1] in make menuconfig you should have: [*] Use CMOS for configuration values
-    This option is also known as CONFIG_USE_OPTION_TABLE in Kconfig.
-Information through SSH
-======================
-board_status.sh can gather information through ssh with the -r
-option.
-
-When using "-r <host>", The script will attempt to log into
-root@<host>.
-In order for "-r <host>" to work, the script has to be able
-to log into the remote host's root account, without having
-to provide a password.
-That can be achieved with the use of SSH keys and ssh-agent.
-
-board_status.sh expects the remote host to have the following
-programs in its path: cbmem, dmesg
-
-Boot log gathering through a serial port
-=======================================
-When using -s </dev/xxx>, board_status.sh starts by retrieving the
-boot log through the serial port.
-
-To produce such logs, power off the board, run board_status.sh
-with the right arguments, power on the board.
-At that point the logs will be displayed by board_status.sh as they
-are produced by the board.
-
-Enter will have to be pressed once the board has booted and is in a
-state where the script is able to log into that board.
-
-Publishing
-==========
-The -u switch will publish the results: It will make a git patch out
-of the status information, that will be directly pushed in the
-board-status repository.
-It expects the user to already have an account in coreboot's gerrit
-instance.
