 -        This provides basic support for the National Semiconductor SCx200
 -        processor.  Right now this is just a driver for the GPIO pins.
 +        This provides basic support for National Semiconductor's
 +        (now AMD's) Geode processors.  The driver probes for the
 +        PCI-IDs of several on-chip devices, so its a good dependency
 +        for other scx200_* drivers.
  
 -        If you don't know what to do here, say N.
 +        If compiled as a module, the driver is named scx200.
  
 -        This support is also available as a module.  If compiled as a
 -        module, it will be called scx200.

 +        This driver provides a clocksource built upon the on-chip
 +        27MHz high-resolution timer.  Its also a workaround for
 +        NSC Geode SC-1100's buggy TSC, which loses time when the
 +        processor goes idle (as is done by the scheduler).  The
 +        other workaround is idle=poll boot option.
