[Qemu-devel] [PATCH v2 06/11] usb/ehci: Add Sysbus Infrastructure

[Peter Crosthwaite]

Add QOM class definition helpers for sysbus attached EHCI implementations.

Signed-off-by: Peter Crosthwaite <peter.crosthwa...@xilinx.com>
---
changed from v1:
Dont create a QOM definition for Sysbus EHCI, rather just add all the bits
and pieces. (Multiple) sysbus EHCI defs can be created by adding to the
type_info[] table.
Use dma_context_memory for sysbus DMA (PMM review)
