The sh_mobile_lcdcfb driver calls interfaces provided by the corresponding "meram" helper. This fails if meram is a module but lcdcfb is built-in.
To work around it, this uses special Kconfig magic to only allow lcdcfb to be built if a) both are modules, b) meram is built-in, or c) meram is disabled and the helpers stubbed out
Changing meram from 'y' to 'm' now forces clcd to be a module as well, which seems to be the desired behavior.
