This patch series adds pxelinux.cfg-style network booting to the s390-ccw
firmware. The core pxelinux.cfg loading and parsing logic has recently
been merged to SLOF, so these patches now just have to make sure to call
the right functions to get the config file loaded and parsed. Once this is
done, the kernel and initrd are loaded separately, and are then glued
together in RAM.

Note that you have to update the roms/SLOF submodule to the latest version
of SLOF first (64c526a6020c3042e3b2a505d5f5f11478d5f2cb). Unfortunately the
SLOF.git mirror on qemu.org currently is not updated anymore (i.e. this also
must be fixed), so you need to use the upstream https://github.com/aik/SLOF
if you want to test the patches right now.
