2017-05-02pc-bios/s390-ccw: get LOADPARM stored in SCP Read InfoFarhan Ali
Obtain the loadparm value stored in SCP Read Info by performing a SCLP Read Info request. Rename sclp-ascii.c to sclp.c to reflect the changed scope of the file.

2015-06-30s390-ccw.img: Consume service interruptsChristian Borntraeger
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 Graf
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>
