pseries: Implement PAPR NVRAM
The PAPR specification requires a certain amount of NVRAM, accessed via RTAS, which we don't currently implement in qemu. This patch addresses this deficiency, implementing the NVRAM as a VIO device, with some glue to instantiate it automatically based on a machine option. The machine option specifies a drive id, which is used to back the NVRAM, making it persistent. If nothing is specified, the driver instead simply allocates space for the NVRAM, which will not be persistent Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Alexander Graf <agraf@suse.de>
