- 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 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.
- This support is also available as a module. If compiled as a
- module, it will be called scx200.
