[Qemu-devel] [PATCH] pseries: Instantiate USB interface when required |

The pseries machine already supports the -vga std option, creating a
graphics adapter. However, this is not very useful without being able to
add a keyboard and mouse as well. This patch addresses this by adding
a USB interface when requested, and automatically adding a USB keyboard
and mouse when VGA is enabled.
This is a stop gap measure to get usable graphics mode on pseries while
waiting for Li Zhang's rework of USB options to go in after 1.2.
