* pc-bios/s390-ccw: define loadparm lengthCollin Walling2018-06-181-1/+1
| | | | | | | | | | | Loadparm is defined by the s390 architecture to be 8 bytes in length. Let's define this size in the s390-ccw bios.

* pc-bios/s390-ccw: get LOADPARM stored in SCP Read InfoFarhan Ali2017-05-021-0/+2
| | | | | | | | | | | | 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.

* S390: ccw firmware: Add sclp outputAlexander Graf2013-04-261-0/+107
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>
