Add initramfs-tools scripts that apply firmware-provided I/O configuration data as auto-configuration during boot. This way, all I/O devices configured by DPM are automatically brought online without further user interaction. This mechanism is active by default. It can be deactivated by specifying the following parameter on the kernel command line: rd.zdev=no-auto Signed-off-by: Peter Oberparleiter <oberpar@linux.vnet.ibm.com> Signed-off-by: Jan Höppner <hoeppner@linux.ibm.com>
