The following series adds support for the Congatec CGEB interface found on some Congatec x86 boards. The CGEB interface is a BIOS interface which provides access to onboard peripherals like I2C busses and watchdogs. It works by mapping BIOS code and searching for magic values which specify the entry points to the CGEB call. The CGEB call is an API provided by the BIOS which provides access to the functions in an ioctl like fashion. For more information about the CGEB API have a look at: http://www.congatec.com/single_news+M5d58c9cd155.html This document only describes the C API, unfortunately not the underlying BIOS interface. Comments very appreciated.
