[Qemu-devel] [PULL 4/5] hw/usb: Add generic sys-bus EHCI controller

[Gerd Hoffmann]

From: Hongbo Zhang <address@hidden>

This patch introduces a new system bus generic EHCI controller.
For the system bus EHCI controller, we've already had "xlnx",
"exynos4210", "tegra2", "ppc4xx" and "fusbh200", they are specific and
only suitable for their own platforms, platforms such as an Arm server,
may need a generic system bus EHCI controller, this patch creates it,
and the kernel driver ehci_platform.c works well on it.
