ohci: add missing break
Make all static TypeInfos const
Since 39bffca2030950ef6efe57c2fac8327a45ae1015 (qdev: register alltypes natively through QEMU Object Model), TypeInfo as used inthe common, non-iterative pattern is no longer amended with informationand should therefore be const....
usb: Add an usb_device_ep_stopped USBDevice method
Some usb devices (host or network redirection) can benefit from knowing whenthe guest stops using an endpoint. Redirection may involve submitting packetsindependently from the guest (in combination with a fifo buffer between the...

usb: tag usb host adapters as not hotpluggable.
Hotplugging them simply doesn't work, so tag them accordingly toavoid users trying and then crashing qemu.
For xhci there is nothing fundamental which prevents hotplug fromworking, we'll "only" need a exit() function which cleans up...

dma: Define dma_context_memory and use in sysbus-ohci
Define a new global dma_context_memory which is a DMAContext correspondingto the global address_space_memory AddressSpace. This can be used bysysbus peripherals like sysbus-ohci which need to do DMA....
usb: split packet result into actual_length + status
Since with the ehci and xhci controllers a single packet can be largerthen maxpacketsize, it is possible for the result of a single packetto be both having transferred some data as well as the transfer to have...
usb: Move short-not-ok handling to the core
After a short-not-ok packet ending short, we should not advance the queue.Move enforcing this to the core, rather then handling it in the hcd code.
This may result in the queue now actually containing multiple input packets...

usb: Add USB_RET_ADD_TO_QUEUE packet result code
This can be used by usb-device code which wishes to process an entire endpointqueue at once, to do this the usb-device code returns USB_RET_ADD_TO_QUEUEfrom its handle_data class method and defines a flush_ep_queue class method...
Rename target_phys_addr_t to hwaddr
target_phys_addr_t is unwieldly, violates the C standard (_t suffixes arereserved) and its purpose doesn't match the name (most target_phys_addr_taddresses are not target specific). Replace it with a finger-friendly,...

usb: unique packet ids
This patch adds IDs to usb packets. Those IDs are (a) supposed to beunique for the lifecycle of a packet (from packet setup until the packetis either completed or canceled) and (b) stable across migration.

usb-ohci: Use universal DMA helper functions
The OHCI device emulation can provide both PCI and SysBus OHCIimplementations. Because of this, it was not previously converted touse the PCI DMA helper functions.
This patch converts it to use the new universal DMA helper functions....
usb: the big rename
Reorganize usb source files. Create a new hw/usb/ directory and moveall usb source code to that place. Also make filenames a bit moredescriptive. Host adapters are prefixed with "hch-" now, usb deviceemulations are prefixed with "dev-". Fixup paths Makefile and include...
usb: zap hw/ush-{ohic,uhci}.h + init wrappers

usb-ohci: DMA writeback bug fixes
This patch fixes two bugs in the OHCI device where the device writesback data to system memory that should be exclusively under thecontrol of the guest side driver.
