Cornelia Huck 22d67ab55a s390-ccw.img: Detect devices with stsch. 
stsch is the canonical way to detect devices. As a bonus, we can
abort the loop if we get cc 3, and we need to check only the valid
devices (dnv set).

Christian Borntraeger 7f61cbc108 s390-ccw.img: replace while loop with a disabled wait on s390 bios

Alexander Graf 92f2ca38b0 S390: ccw firmware: Add main program 
This C file is the main driving piece of the s390 ccw firmware. It
provides a search for a workable block device, sets it as the default
to boot off of and boots from it.
