Time passed, the netboot code proved its usefulness, and the build system nowadays makes sure that the SLOF module is checked out if you have a s390x compiler available for building the s390-ccw bios. In fact, the possibility to build the s390-ccw.img without s390-netboot.img has been removed in commit bf6903f6944f ("pc-bios/s390-ccw: always build network bootloader") already. So it does not make too much sense anymore to keep the netboot code in a separate binary. To make it easier to support a more flexible boot process soon that supports more than one boot device via the bootindex properties, let's finally merge the netboot code into the main s390-ccw.img binary now.
