openwrt-xburst/target/linux/ixp4xx/patches-3.3/300-avila_support.patch
nbd dcb25b7b8a ixp4xx: update Gateworks Avila board support 
Several new features for newer boards:
 - add additional UARTs present on some boards
 - add additional LEDs present on some boards
 - add HSS audio device codec present on some boards
 - add support for GSC present on some boards
 - add per model setup support for newer boards
 - set FLASH window per-model for boards with larger FLASH

Some fixes:
 - add IRQ mapping for additional PCI devices (USB Host)
