# Hardware

QMK runs on a variety of hardware. If your processor can be targeted by [LUFA](http://www.fourwalledcubicle.com/LUFA.php) or [ChibiOS](http://www.chibios.com) you can probably get QMK running on it. This section explores getting QMK running on, and communicating with, hardware of all kinds.

Subject: [PATCH 13/36] MTD: lantiq: xway: fix invalid operator

xway_read_byte should use a logic or and not an add operator when working out
the nand address.
