b3cbcd902d usb: ehci: do not invalidate a NULL buffer
Its a valid use case to call ehci_submit_async() with a NULL buffer
with length 0. E.g. from usb_set_configuration().

As invalidate_dcache_range() isn't able to judge if the address
NULL is valid or not (depending on the SoC hardware configuration it
might be valid) do the check in ehci_submit_async() as here we know
that we don't have to invalidate such a buffer.

45157d2764 dm: usb: ehci: avoid possible NULL dereference
Currently we check in ehci_shutdown() if ctrl is NULL after
dereferencing it.

Before this we have already dereferenced ctrl, ctrl->hccr,
and ctrl->hcor in ehci_get_portsc_register(), ehci_submit_root(),
and hci_common_init().

A better approach is to already check ctrl, ctrl->hccr, and ctrl->hcor
during the initialization in ehci_register() and usb_lowlevel_init()
and signal an error here via the return code.

9829ce2ff2 usb: ehci: Fix accessors for big-endian platforms and descriptors
Commit 9000eddbae ("drivers/usb/ehci: Use platform-specific accessors")
broke USB 2.0 on big-endian platforms because for them writel/readl()
does automatic conversion of BE data to LE.

Proper implementation requires to use "raw" variant of these accessors
which read/write data without messing with endianess.

While at it replace cpu_to_be32() to be32_to_cpu() in readl() to
keep sane semantics.

9b643e312d treewide: replace with error() with pr_err()
U-Boot widely uses error() as a bit noisier variant of printf().

This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:

  # define __compiletime_error(message) __attribute__((error(message)))

This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux.  (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)

Let's convert error() into now treewide-available pr_err().

Done with the help of Coccinelle, excluing tools/ directory.

The semantic patch I used is as follows:

// <smpl>
@@@@
-error
+pr_err
 (...)
// </smpl>

d4efefe32e dm: usb: Fix broken usb_stop()
At present we only do device_remove() during usb stop. The DM API
device_remove() only marks the device state as inactivated, but
still keeps its USB topology (eg: parent, children, etc) in the DM
device structure. There is no issue if we only start USB subsystem
once and never stop it. But a big issue occurs when we do 'usb stop'
and 'usb start' multiple times.

Strange things may be observed with current implementation, like:
- the enumeration may report only 1 mass storage device is detected,
  but the total number of USB devices is correct.
- USB keyboard does not work anymore after a bunch of 'usb reset'
  even if 'usb tree' shows it is correctly identified.
- read/write flash drive via 'fatload usb' may complain "Bad device"

In fact, every time when USB host controller starts the enumeration
process, it takes random time for each USB port to show up online,
hence each USB device may appear in a different order from previous
enumeration, and gets assigned to a totally different USB address.
As a result, we end up using a stale USB topology in the DM device
structure which still reflects the previous enumeration result, and
it may create an exact same DM device name like generic_bus_0_dev_7
that is already in the DM device structure. And since the DM device
structure is there, there is no device_bind() call to bind driver to
the device during current enumeration process, eventually creating
an inconsistent software representation of the hardware topology, a
non-working USB subsystem.

The fix is to clear the unused USB topology in the usb_stop(), by
calling device_unbind() on each controller's root hub device, and
the unbinding will unbind all of its children automatically.

For Sandbox, we need scan the device tree each time when we start
the USB stack, in order to re-create the emulated USB devices and
bind drivers for them before we actually do the driver probe.

84aa8536f0 usb: sandbox: Fix emulator device select logic in usb_emul_find_devnum()
Current emulator select logic in usb_emul_find_devnum() is to test
the USB address. The USB address of the device being enumerated is
initialized to zero at the beginning of the enumeration process in
usb_setup_device(). At this point, the saved USB address in the
platform data has not been assigned to any valid USB address either.
This means: the logic will select an emulator device according to
its sequence of declaring order in the device tree. Take test.dts
for example, flash-stick@0 will be selected before flash-stick@1.
But unfortunately such logic is wrong.

In fact USB devices show up in a random order during the enumeration
which means usb_emul_find_devnum() may be called on port 3 for keyb@3
before on port 0 for flash-stick@0.

To fix this, we introduce a new emulator uclass specific platdata
to store the USB device's port number on its parent hub, and update
the logic to test the port number instead.

7489d22a3c usb: xhci: Set number of event segments and entries to 1
The Linux kernel driver sets the number of event segments and entries
to 1 , while the initial import of the xhci code set that values to 3
for reasons unknown. While most controllers are fine with more event

Set the number of event segments and event entries back to 1 to allow
such controllers to work with U-Boot xHCI stack. Note that the Renesas
controller correctly indicates ERST Max = 1 in HCSPARAMS2[7:4] .

xHCI spec says: the values of the 'route string' field shall be
initialized by the first 'Address Device' command issued to a
device slot, and shall not be modified by any other command.

So far U-Boot does not program this field, and it does not prevent
SS device directly attached to root port, or HS device behind an HS
hub, from working, due to the fact that 'route string' is used by
the xHC to target SS packets. But in order to enumerate devices
behind an SS hub, this field must be programmed.

With this commit and along with previous commits, now SS & HS devices
attached to a USB 3.0 hub can be enumerated by U-Boot.

As usual, this new feature is only available when DM is on.
