uio_usbdebug: User-space-i/o framework for usbdebug
uio_usbdebug enables you to debug coreboot's usbdebug driver inside a running operating system (only Linux at this time). This comes very handy if you're hacking the usbdebug driver and don't have any other debug output from coreboot itself. Currently, only Intel chipsets are supported.
