2015-06-30s390-ccw.img: Consume service interruptsChristian Borntraeger1-0/+1
We have to consume the outstanding service interrupt after each service call, otherwise a correct implementation will return CC=2 on subsequent service calls.

2013-04-26S390: ccw firmware: Add sclp outputAlexander Graf1-0/+81
In order to communicate with the user, we need an I/O mechanism that he can read. Implement SCLP ASCII support, which happens to be the default in the s390 ccw machine. This file is missing read support for now. It can only print messages. Signed-off-by: Alexander Graf <agraf@suse.de>
