This defines a choice group and accepts any of the above attributes as

options. A choice can only be of type bool or tristate.  If no type is

specified for a choice, its type will be determined by the type of

the first choice element in the group or remain unknown if none of the

choice elements have a type specified, as well.



While a boolean choice only allows a single config entry to be

selected, a tristate choice also allows any number of config entries

to be set to 'm'. This can be used if multiple drivers for a single

hardware exists and only a single driver can be compiled/loaded into

the kernel, but all drivers can be compiled as modules.
