s390/pci: CLP interface
CLP instructions are used to query the firmware about detected PCI functions, the attributes of those functions and to enable or disable a PCI function. The CLP interface is the equivalent to a PCI bus scan. Signed-off-by: Jan Glauber <jang@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
