From 8ffd9f4dd41f0423f0df8bef8f2e25ab4bb1a3f3 Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Tue, 17 Mar 2015 14:52:54 +0100 Subject: [PATCH] hw/usb: Include USB files only if necessary Boards that do not include an USB controller should not provide USB devices. However, when running "qemu-system-s390x -device help" for example, there's still a usb-hub, usb-kbd, usb-mouse and usb-tablet in the list of "supported" devices. Let's fix that by compiling and linking the USB files only if it is really necessary.
