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