2c79a775ed - Add more defines to limit USB memory usage and number of allocations
in reduced memory systems.

- Split allocation and freeing of the configuration descriptor into a separate
function, so that the configuration descriptor can be made fixed size
to save memory allocations. This applies for both device and host mode.

23de050b72 - Make quirk for reading device descriptor from broken USB devices.
Else they won't enumerate at all:
hw.usb.full_ddesc=1
- Reduce the USB descriptor read timeout from 1000ms to
500ms. Typical value for LOW speed devices is 50-100ms.
- Enumerate USB device a maximum of 3 times when a port
connection change event is detected, before giving up.

a18a7a414a Resolve a LOR after r246616. Protect control requests using the USB device
enumeration lock. Make sure all callers of usbd_enum_lock() check the return
value. Remove the control transfer specific lock. Bump the FreeBSD version
number, hence external USB modules may need to be recompiled due to a USB
device structure change.

d2b99310b1 Modify the FreeBSD USB kernel code so that it can be compiled directly
into the FreeBSD boot loader, typically for non-USB aware BIOSes, EFI systems
or embedded platforms. This is also useful for out of the system compilation
of the FreeBSD USB stack for various purposes. The USB kernel files can
now optionally include a global header file which should include all needed
definitions required to compile the FreeBSD USB stack. When the global USB
header file is included, no other USB header files will be included by
default.

Add new file containing the USB stack configuration for the
FreeBSD loader build.

Replace some __FBSDID()'s by /* $FreeBSD$ */ comments. Now all
USB files follow the same style.

Use cases:
 - console in loader via USB
 - loading kernel via USB

3750641271 Make several timing parameters of the USB enumeration sequence tuneable.
Also update the port reset time from 250ms to 50ms. Some USB devices
have a hard limit in hardware at 222ms for the port reset time and will
not enumerate unless this delay is closer to the usb.org defined value.
This patch can fix enumeration with some USB devices.

a5cf1aaaff Add support for the so-called streams feature of BULK endpoints
in SUPER-speed mode, USB 3.0.

This feature has not been tested yet, due to lack of hardware.

This feature is useful when implementing protocols like UASP,
USB attached SCSI which promises higher USB mass storage throughput.

This patch also implements support for hardware processing of endpoints
for increased performance. The switching to hardware processing
of an endpoint is done via a callback to the USB controller driver. The
stream feature is implemented like a variant of a hardware USB protocol.

USB controller drivers implementing device mode needs to be updated to
implement the new "xfer_stall" USB controller method and remove the
"xfer" argument from the "set_stall" method.

The API's toward existing USB drivers are preserved. To setup a USB transfer
in stream mode, set the "stream_id" field of the USB config structure to
the desired value.

The maximum number of BULK streams is currently hardcoded and limited to 8
via a define in usb_freebsd.h.

All USB drivers should be re-compiled after this change.

LibUSB will be updated next week to support streams mode. A new IOCTL to
setup BULK streams as already been implemented. The ugen device nodes
currently only supports stream ID zero.

The FreeBSD version has been bumped.

963169b4af This commit adds full support for USB 3.0 devices in host and device
mode in the USB core.  The patch mostly consists of updating the USB
HUB code to support USB 3.0 HUBs. This patch also add some more USB
controller methods to support more active-alike USB controllers like
the XHCI which needs to be informed about various device state events.

USB 3.0 HUBs are not tested yet, due to lack of hardware, but are
believed to work.

After this update the initial device descriptor is only read twice
when we know that the bMaxPacketSize is too small for a single packet
transfer of this descriptor.

2df1e9a62a If a USB device is suspended and a USB set config request is issued when the
USB enumeration lock is locked, then the USB stack fails to resume the device
because locking the USB enumeration lock is part of the resume procedure. To
solve this issue a new lock is introduced which only protects the suspend and
resume callbacks, which can be dropped inside the usbd_do_request_flags()
function, to allow suspend and resume during so-called enumeration operations.

fde875265f Provide a better commit log for r190735, forced by making a whitespace change.
Refactor how we interface with the root HUB. This is achieved by making a
direct call from usb2_do_request to the host controller for root hub requests,
this call will perform the controller specific register read/writes and return
the error code.

This cuts out a lot of code in the host controller files and saves one thread
per USB bus.

- make usb2_power_mask_t 16-bit
- remove "usb2_config_sub" structure from "usb2_config". To compensate for this
  "usb2_config" has a new field called "usb_mode" which select for which mode
  the current xfer entry is active. Options are: a) Device mode only b) Host
  mode only (default-by-zero) c) Both modes.  This change was scripted using
  the following sed script: "s/\.mh\././g".
- the standard packet size table in "usb_transfer.c" is now a function, hence
  the code for the function uses less memory than the table itself.
