Ups, sorry. It seems I forgot to git add
arch/x86/platform/congatec/Makefile. It should look like this:
obj-$(CONFIG_CONGATEC_CGEB) += congatec-cgeb.o
I will include this next time.
Any other comments to this series? Is the base cgeb support ok to
include?

[PATCH 1/3] x86: Add basic support for the Congatec CGEB BIOS interface
The Congatec CGEB is a BIOS interface found on some Congatec x86
modules. It provides access to on board peripherals like I2C busses
and watchdogs. This driver contains the basic support for accessing
the CGEB interface and registers the child devices.

[PATCH 1/3] x86: Add basic support for the Congatec CGEB BIOS interface
The Congatec CGEB is a BIOS interface found on some Congatec x86
modules. It provides access to on board peripherals like I2C busses
and watchdogs. This driver contains the basic support for accessing
the CGEB interface and registers the child devices.
