QQ2440 is an ARM based development board. It is commonly found together
with LCD displays but mine was not so I am not able to support them yet.
Networking bits are already mainlined.
This patch applies cleanly to 2.6.39-rc1

This is v3 updated for 2.6.39-rc1. It now uses S3C common UDC pullup
pin support and the generic gpio-leds driver.
