111           Partitionable IBM Power5 ppc64 machines allow hosting of
112           firmware virtual consoles from one Linux partition by
113           another Linux partition.  This driver allows console data
114           from Linux partitions to be accessed through TTY device
115           interfaces in the device tree of a Linux partition running
116           this driver.
117 
118           To compile this driver as a module, choose M here: the
119           module will be called hvcs.  Additionally, this module
120           will depend on arch specific APIs exported from hvcserver.ko
121           which will also be compiled when this driver is built as a
122           module.
