USB: add SPDX identifiers to all remaining Makefiles It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. This updates the remaining drivers/usb/Makefile that were missing SPDX identifiers. They all get the following identifier: SPDX-License-Identifier: GPL-2.0 The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text.

USB: ehci,dbgp,early_printk: split ehci debug driver from early_printk.c Move the dbgp early printk driver in advance of refactoring and adding new code, so the changes to this code are tracked separately from the move of the code. The drivers/usb/early directory will be the location of the current and future early usb code for driving usb devices prior initializing the standard interrupt driven USB drivers.

usb: makefile cleanup For all modules, change <module>-objs to <module>-y; remove if-statements and replace with lists using the kbuild idiom; move flags to the top of the file; and fix alignment while trying to maintain the original scheme in each file. None of the dependencies are modified.

usb/early: Add driver for xhci debug capability XHCI debug capability (DbC) is an optional but standalone functionality provided by an xHCI host controller. Software learns this capability by walking through the extended capability list of the host. XHCI specification describes DbC in section 7.6. This patch introduces the code to probe and initialize the debug capability hardware during early boot. With hardware initialized, the debug target (system on which this code is running) will present a debug device through the debug port (normally the first USB3 port). The debug device is fully compliant with the USB framework and provides the equivalent of a very high performance (USB3) full-duplex serial link between the debug host and target. The DbC functionality is independent of the xHCI host. There isn't any precondition from the xHCI host side for the DbC to work. One use for this feature is kernel debugging, for example when your machine crashes very early before the regular console code is initialized. Other uses include simpler, lockless logging instead of a full-blown printk console driver and klogd.
