####################################################### # # Main options file for coreboot # # Each option used by a part must be defined in # this file. The format for options is: # # define # default | {} | "" | none # format "" # export always | used | never # comment "" # end # # where # # is the name of the option # is a numeric expression # is a string # # Either a default value or 'default none' must # be specified for every option. An option # specified as 'default none' will not be exported # (i.e. will remain undefined) unless it has # been assigned a value. # # Option values can be an immediate expression that # evaluates to a numeric value, a delayed expression # (surrounded by curley braces), or a string # (surrounded by double quotes.) # # Immediate expressions are evaluated at the time an # option is defined or set and the numeric result # becomes the value of the option. # # Delayed expression are evaluated at the time the # option is used, either in another expression or # when being exported. # # String values will have the double quotes removed # automatically. # # Format strings determine the print format that is # used when exporting options. The default format # is "%s" for strings and "%d" for numbers. # # Exported options generate entries in the # Makefile.settings file. Options can be always # exported, exported only if used, or never exported. # # A comment string must be supplied for every option. # ####################################################### ############################################### #
