I was able to test & verify it on my local machine using latest Qemu master and linux 5.5.0. I just had to add the -usb flag to the Qemu command and re-compile linux with CONFIG_USB_STORAGE.

Instantiate EHCI and OHCI controllers on Allwinner A10. The first patch in the series moves the declaration of EHCISysBusState from hcd-ohci.c to hcd-ohci.h. This lets us add the structure to AwA10State. Similar, TYPE_SYSBUS_OHCI is moved to be able to use it outside its driver. The second patch introduces the ehci-sysbus property "companion-enable". This lets us use object_property_set_bool() to enable companion mode. The third patch instantiates EHCI and OHCI ports for Allwinner-A10 and marks the OHCI ports as companions of the respective EHCI ports. Tested by attaching various high speed and full speed devices, and by booting from USB drive. v3: Rebased to master v2: Add summary Rewrite to instantiate OHCI in companion mode; add patch 2/3 Merge EHCI and OHCI instantiation into a single patch ---------------------------------------------------------------- Guenter Roeck (3): hw: usb: hcd-ohci: Move OHCISysBusState and TYPE_SYSBUS_OHCI to include file hcd-ehci: Introduce "companion-enable" sysbus property arm: allwinner: Wire up USB ports hw/arm/allwinner-a10.c | 43 ++++++++++++++++++++++++++++++++++++++++++ hw/usb/hcd-ehci-sysbus.c | 2 ++ hw/usb/hcd-ohci.c | 15 --------------- hw/usb/hcd-ohci.h | 16 ++++++++++++++++ include/hw/arm/allwinner-a10.h | 6 ++++++ 5 files changed, 67 insertions(+), 15 deletions(-)
