RH-Commit: [5/23] ff245b81b45ddd3a78343d1a8cfdd725a8255d87 (thuth/qemu-kvm-cs9)
|
||
|
|
|
||
|
|
Since the netboot code has now been merged into the main s390-ccw.img
|
||
|
|
binary, we don't need the separate s390-netboot.img anymore. Remove
|
||
|
|
it and the code that was responsible for loading it.
|
||
