[PULL 06/55] hw/isa/vt82c686: Instantiate IDE function in host device |
Date: |

From: Bernhard Beschow <shentey@gmail.com>
The IDE function is closely tied to the ISA function (e.g. the IDE
interrupt routing happens there), so it makes sense that the IDE
function is instantiated within the south bridge itself.
