- If you have a Ralink RT288x/RT305x SoC based board and want to use the
- serial port, say Y to this option. The driver can handle up to 2 serial
- ports. If unsure, say N.
+ Selecting this option will add support for the alternate register
+ layout used by Ralink RT288x/RT305x, Alchemy Au1xxx, and some others.
+ If unsure, say N.
