This adds stack layer for eXtensible Host Controller Interface
which facilitates use of USB 3.0 in host mode.
Adapting xHCI host controller driver in linux-kernel
by Sarah Sharp to needs in u-boot.
Initial porting from Linux kernel version 3.4, with following
top commit history of drivers/usb/host/xhci* :
cf84055 xHCI: Cleanup isoc transfer ring when TD length mismatch found
This adds the basic xHCI host controller driver with bare minimum
features:
- Control/Bulk transfer support has been added with required
infrastructure for necessary xHC data structures.
- Stream protocol hasn't been supported yet.
- No support for quirky devices has been added.

Macros defining bmRequestType field of USB device request,
given in table 9.2 USB 2.0 spec, are rather generic macros
which can be further used by other Host controller stacks.
So moving them to usb_defs header.

The EHCI controller has some very specific requirements for the USB 2.0
port test modes, which were not closely followed in the initial test
mode commit. It demands that the host controller is completely shut down
(all ports suspended, Run/Stop bit unset) when activating test mode, and
will not work on an already enumerated port.
This patch fixes that by introducing a new ehci_shutdown() function that
closely follows the procedure listed in EHCI 4.14. Also, when we have
such a function anyway, we might as well also use it in
usb_lowlevel_stop() to make the normal host controller shutdown cleaner.

Currently we have the following behavior in ehci_hcd_init()
- Read csmr1 register, clear bit 26 and then set bit 26.
However a little bit later we call set_usb_phy_clk() which clears bit 26, so
let's get rid of the unnecessary code.

usb_lowlevel_init() allocates a new periodic_list each time it is invoked,
without freeing the original list. Since it is initialized later on in the code,
just reuse the first-allocated list in future invocations of usb_lowlevel_init.

Fixes NFS root problems with Beagle (3530 ES1.0) when used with
external USB-ethernet adapter and "USB start" command used within
u-boot.
Soft resetting the UHH module causes instability issues on
all OMAPs so we just avoid it.
See OMAP36xx Errata
i571: USB host EHCI may stall when entering smart-standby mode
i660: USBHOST Configured In Smart-Idle Can Lead To a Deadlock
On OMAP4/5, soft-resetting the UHH module can put it into
Smart-Idle mode and lead to a deadlock.
On OMAP3 this doesn't seem to be the case but still instabilities
are observed on beagle (3530 ES1.0) if soft-reset is used.

Commit 8f62ca6 "usb: ehci: Support interrupt transfers via periodic list"
didn't include any cache management in the new interrupt transfer path.
It also added an extra write to or_asynclistaddr in usb_lowlevel_init(),
without having flushed out the data there.
Add the missing cache management calls, so that the code works again.
This allows the USB keyboard on Tegra's Seaboard/Springbank boards to
work.

This patch adds support to both Faraday FUSBH200 and FOTG210,
the differences between Faraday EHCI and standard EHCI are
listed bellow:
1. The PORTSC starts at 0x30 instead of 0x44.
2. The CONFIGFLAG(0x40) is not only un-implemented, and
also has its address space removed.
3. Faraday EHCI is a TDI design, but it doesn't
compatible with the general TDI implementation
found at both U-Boot and Linux.
4. The ISOC descriptors differ from standard EHCI in
several ways. But since U-boot doesn't support ISOC,
we don't have to worry about that.

There is at least one non-EHCI compliant controller (i.e. Faraday EHCI)
not only leave RESERVED and CONFIGFLAG registers un-implemented
but also has their address spaces removed.
As an result, the PORTSC register of Faraday EHCI always
starts from 0x30 instead of 0x44 in standard EHCI.
So that we'll need a weak-aliased function for abstraction.

1. The 'index' of ehci_submit_root() is not always > 0.
e.g.
While it gets invoked from usb_get_descriptor(),
the 'index' is always a '0'. (See ch.9 of USB2.0)
2. The PORTSC register is not always required, and thus it
should only report a port error when necessary.
It would cause a port scan failure if the ehci_submit_root()
always gets terminated by a port error.

This commit broke USB2 on link (Chromebook Pixel):
020bbcb usb: hub: Power-cycle on root-hub ports
However the root cause seems to be a missing mask and missing 'break'
in ehci-hcd.c. This patch fixes both.
On link, 'usb start' with a USB keyboard and memory stick inserted now
finds both. The keyboard works as expected. Also ext2ls shows a directory
listing from the memory stick.

Interrupt transfers aren't meant to be used from the async list
(the EHCI spec indicates trouble with low/full-speed intr on async).
Build a periodic list instead, and provide an API to make use of it.
Then, use that API from the existing interrupt transfer API.
This provides support for USB keyboards using EHCI.
Use timeouts to ensure we cannot get stuck in the keyboard scanning
if something wrong happens (USB device unplugged or fatal I/O error)

This moves the Tegra USB implementation into the drivers/usb/host
directory. Note that this merges the old
/arch/arm/cpu/armv7/tegra20/usb.c file into ehci-tegra.c. No code
changes, just moving stuff around.
v2: While at it also move some defines and the usb.h header file to make
usb driver usable for Tegra30.
NOTE: A lot more work is required to properly init the PHYs and PLL_U on
Tegra30, this is just to make porting easier and it does no harm here.

Linux usb/ch9.h seems to have all the same information (and more)
as usbdescriptors.h so use the former instead of the later one.
As a consequense of this change USB_SPEED_* values don't correspond
directly to EHCI speed encoding anymore, I've added necessary
recoding in EHCI driver. Also there is no point to put speed into
pipe anymore so it's removed and a bunch of host drivers fixed to
look at usb_device->speed instead.
Old usbdescriptors.h included is not removed as it seems to be
used by old USB device code.
This makes usb.h and usbdevice.h incompatible. Fortunately the
only place that tries to include both are the old MUSB code and
it needs usb.h only for USB_DMA_MINALIGN used in aligned attribute
on musb_regs structure but this attribute seems to be unneeded
(old MUSB code doesn't support any DMA at all).
