`mmc_initialize` might be called multiple times leading to the mmc-controllers
being initialised twice, and initialising the `mmc_devices` list head twice
which may lead to memory leaks.

Remove the incorrect PEX macros from the DDR header. And insert the

This patch adds the DDR3 setup and training code taken from the Marvell
U-Boot repository. This code used to be included as a binary (bin_hdr)
into the Armada A38x boot image. Not linked with the main U-Boot. With this
code addition and the serdes/PHY setup code, the Armada A38x support
in mainline U-Boot is finally self-contained. So the complete image
for booting can be built from mainline U-Boot. Without any additional
external inclusion.
Note:
This code has undergone many hours (days!) of coding-style cleanup and
refactoring. It still is not checkpatch clean though, I'm afraid. As the
factoring of the code has so many levels of indentation that many lines
are longer than 80 chars.

With the upcoming addition of the Armada 38x DDR support, which is not
compatible to the Armada XP DDR init code, we need to introduce a new
directory infrastructure. To support multiple Marvell DDR controller.
This will be the new structure:
drivers/ddr/marvell/axp
Supporting Armada XP (AXP) devices (and perhaps Armada 370)
drivers/ddr/marvell/a38x
Supporting Armada 38x devices (and perhaps Armada 39x)

The macro cpu_relax() is defined by several headers in different
ways.
arch/{arm,avr32,mips}/include/asm/processor.h defines it as follows:
#define cpu_relax() barrier()
On the other hand, include/linux/compat.h defines it as follows:
#define cpu_relax() do {} while (0)
If both headers are included from the same source file, the warning
warning: "cpu_relax" redefined [enabled by default]
is displayed.
It effectively makes it impossible to include <linux/compat.h>
from some sources. Drop the latter.

FASTBOOT is defined both by CONFIG_USB_FUNCTION_FASTBOOT AND CONFIG_CMD_FASTBOOT, so it doesn't
make much sense to have a CONFIG_USB_FASTBOOT prefix for fastboot-specific options, especially
given that other config options for fastboot use the CONFIG_FASTBOOT prefix.
This replaces the CONFIG_USB_FASTBOOT prefix with CONFIG_FASTBOOT, for consistency.

Recent versions of the fastboot tool will query the partition type before doing
an operation on a partition (such as erase, flash, etc). It will then submit
the operation as soon as the response for the partition type is received.
Usually, the MUSB controller will see that the partition type request return
status was read by the host at the very same time as the actual operation
request is submitted by the host. However, the operation will be read first
(int_rx is handled first in musb_interrupt) and after it is completed, the
fastboot USB gadget driver will send another return status. Hence, this happens
before the musb gadget framework has had a chance to handle the previous
acknowledgement that the host read the return status and dequeue the request.
The host will then usually empty the FIFO by the time musb_interrupt gets around
handling the return status acknowledgement (for the previous request, this is
still on the same musb_interrupt call), so no other interrupt is generated and
the most recent return status acknowledgement remains unaccounted for.
It will then be used as a response for the next command, and the proper response
for it will be delayed to the next command, and so on.
Dequeuing the previous IN request in the fastboot code ensures that no previous
return status remains. It is acceptable to do it since there is no callback to
it anyways.

This avoids handling requests that have an error status or no data.
In particular, this avoids showing unnecessary error messages when the USB
gadget gets disconnected (e.g. with fastboot continue) and the fastboot USB
gadget driver sends an error back to the host (that has disconnected already).

Weak versions of board_usb_init and board_usb_cleanup are defined in common USB
host code, but it is also used for USB device gadgets, so we also need a weak
definition of it when there is no USB host enabled.
Both weak definitions do not conflict.

In Linux USB_DEVICE() is used to declare a USB device by vendor/device ID.

At present USB Ethernet does not work with CONFIG_DM_ETH. Add driver model
support to this feature, so that it can work alongside other Ethernet
devices with driver model.
It was found that quite a bit of code is common in most of the USB Ethernet
drivers. Add this code to the common layer to reduce the amount of duplicate
code needed in USB Ethernet drivers when CONFIG_DM_ETH is used.

Some devices can take a long time to work out whether they have a new packet
or now. For example the ASIX USB Ethernet dongle can take 5 seconds to do
this, since it waits until it gets a new packet on the wire before allowing
the USB bulk read packet to be submitted.
At present with driver mode the Ethernet receive code reads 32 packets. This
can take a very long time if we must wait for all 32 packets. The old code
(before driver model) worked by reading a single set of packets from the USB
device, then processing all the packets with in. It would be nice to use
the same behaviour with driver model.
Add a flag to the receive method which indicates that the driver should try
to find a packet if available, by consulting the hardware. When the flag is
not set, it should just return any packet data it has already received. If
there is none, it should return -EAGAIN so that the loop will terminate.

At present all PCI devices must be present in the device tree in order to
be used. Many or most PCI devices don't require any configuration other than
that which is done automatically by U-Boot. It is inefficent to add a node
with nothing but a compatible string in order to get a device working.
Add a mechanism whereby PCI drivers can be declared along with the device
parameters they support (vendor/device/class). When no suitable driver is
found in the device tree the list of such devices is consulted to determine
the correct driver. If this also fails, then a generic driver is used as
before.
The mechanism used is very similar to that provided by Linux and the header
file defintions are copied from Linux 4.1.

Allow musb_platform_enable to return an error code and propagate it up to
usb_lowlevel_init().
This allows moving the checks for an external vbus being present to be
moved from platform_init to platform_enable, so that the user can unplug a
charger, plug in a host adapter with a usb-device, do a "usb reset" and
have things working.
This also allows adding a check for the id-pin to platform_enable, so that
it can short circuit the 1s delay in usb_lowlevel_init() when no host cable
is plugged in and thus waiting for a device to show up is useless.
Note that all the changes to code shared with the kernel are wrapped in
the kernel.

On some single port (otg) controllers there is no emulated root hub, so
the first child (if any) may be one of: UCLASS_MASS_STORAGE,
UCLASS_USB_DEV_GENERIC or UCLASS_USB_HUB.
All three of these (and in the future others) are suitable for our
purposes, remove the check for the device being a hub, and add a check to
deal with the fact that there may be no child-dev.

Now that we unbind usb devices from usb_stop() usb_find_child() is
only necessary to deal with emulated usb devices.
Rename it to make this clear and add a #ifdef to make it a nop in
other cases.
Note the #ifdef turns usb_find_emul_child() into a nop, rather then not
building it and adding another #ifdef to the caller, this is done this way
because adding a #ifdef to the caller is somewhat hairy.

On an usb stop instead of leaving orphan usb devices behind simply remove
them.
The result of this commit is best seen in the output of "dm tree" after
plugging out an usb hub with 2 devices plugges in and plugging in a keyb.
instead, before this commit the output would be:
usb [ + ] `-- sunxi-musb
usb_hub [ ] |-- usb_hub
usb_mass_st [ ] | |-- usb_mass_storage
usb_dev_gen [ ] | `-- generic_bus_0_dev_3
usb_dev_gen [ + ] `-- generic_bus_0_dev_1
Notice the non active usb_hub child and its 2 non active children. The
first child being non-active as in this example also causes usb_get_dev_index
to return NULL when probing the first child, which results in the usb kbd
code not binding to the keyboard.
With this commit in place the output after swapping and "usb reset" is:
usb [ + ] `-- sunxi-musb
usb_dev_gen [ + ] `-- generic_bus_0_dev_1
As expected, and usb_get_dev_index works properly and the keyboard works.
