2013-04-26S390: ccw firmware: Add sclp outputAlexander Graf1-0/+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>
