Add support for BLS zipl

[schaefi]

Add support for

<bootloader name="zipl" .../>

to support BLS based zipl configuration. This Fixes #2481

I'm still testing the different boot disks for s390 which will need a bit of time

• [x] SCSI disk
• [x] FBA (byte array) DASD disk
• [x] CDL (DASD 4k) disk

Can we make sure we have a test image with Rawhide s390x to validate this?

yes it would be good to have integration tests for this code. I will add one ... next week

Ok for me things are working now. Please find the integration tests here:

• https://build.opensuse.org/project/show/Virtualization:Appliances:Images:Testing_s390:rawhide

The Physical profile is for 4k DASD targets whereas the Virtual profile is for zFCP, FBA or virtual (e.g qemu) targets with 512b blocksize

I have tested on s390 itself but also in qemu. If you want to test in qemu please call

qemu-system-s390x -m 4096 -nographic -drive if=none,id=dr1,file=kiwi-test-image-disk.s390x-1.42.1-Virtual-Build10.5.qcow2 -device virtio-blk,drive=dr1,bootindex=1

Thanks
