Add a dm_ prefix to driver model I2C functions so that we can keep the old
ones around.
This is a little unfortunate, but on reflection it is too difficult to
change the API. We can undo this rename when most boards and drivers are
converted to use driver model for I2C.

At present U-Boot sort-of supports the standard way of reading GPIOs from
device tree nodes, but the support is incomplete, a bit clunky and only
works for GPIO bindings where #gpio-cells is 2.
Add new functions to request GPIOs, taking full account of the device
tree binding. These permit requesting a GPIO with a simple call like:
gpio_request_by_name(dev, "cd-gpios", 0, &desc, GPIOD_IS_IN);
This will request the GPIO, looking at the device's node which might be
this, for example:
cd-gpios = <&gpio TEGRA_GPIO(B, 3) GPIO_ACTIVE_LOW>;
The GPIO will be set to input mode in this case and polarity will be
honoured by the GPIO calls.
It is also possible to request and free a list of GPIOs.

These types are problematic because they are typically declared in a
non-standard way in U-Boot. For example, U-Boot uses 'long long' for
int64_t even on a 64-bit machine whereas stdint.h uses 'long'.
Similarly, U-Boot always uses 'long' for intptr_t whereas stdint.h mostly
uses 'int'.
This simple test script runs a few toolchains on a few archs to check for
warnings.

The run command treats each argument an an environment variable. It gets the
value of each variable and executes it as a command. If an environment
variable contains a newline and the hush cli is used, it is supposed to
execute each line one after the other.
Normally a newline signals to hush to exit - this is used in normal command
line entry - after a command is entered we want to return to allow the user
to enter the next one. But environment variables obviously need to execute
to completion.
Add a special case for the execution of environment variables which
continues when a newline is seen, and add a few tests to check this
behaviour.
Note: it's not impossible that this may cause regressions in other areas.
I can't think of a case but with any change of behaviour with limited test
coverage there is always a risk. From what I can tell this behaviour has
been around since at least U-Boot 2011.03, although this pre-dates sandbox
and I have not tested it on real hardware.

Various misc enhancements to dfu_gadget_test.sh:
* After every write (download), perform a write to a different file
with different data. This ensures that the DFU buffer's content is
replaced, so that if the read (upload) succeeds, we know that the
correct data was actually read from the storage device, rather than
simply being left over in the DFU buffer. This requires two alt
setting names to be passed to the script, and a dummy data file to
be generated by dfu_gadget_test_init.sh.
* Fix the assumption that dfu_gadget_test.sh is run from the directory
that contains it, by cd'ing to that directory before invoking
./dfu_gadget_test_init.sh.
* Use $DIR$RCV_DIR consistently, rather than using plain $RCV_DIR in
some places.
* Add 959, 961 test file sizes, to be consistent with having one
more than and one less than all the other "round" sizes 64, 128, and
4096.
* Remove references to $BKP_DIR from dfu_gadget_test_init.sh, since it

Some device types can have child devices and want to store information
about them. For example a USB flash stick attached to a USB host
controller would likely use this space. The controller can hold
information about the USB state of each of its children.
The data is stored attached to the child device in the 'parent_priv'
member. It can be auto-allocated by dm when the child is probed. To
do this, add a per_child_auto_alloc_size value to the parent driver.

Devices can have childen that can be addressed by a simple index, the
sequence number or a device tree offset. Add functions to access a child
in each of these ways.
The index is typically used as a fallback when the sequence number is not
available. For example we may use a serial UART with sequence number 0 as
the console, but if no UART has sequence number 0, then we can fall back
to just using the first UART (index 0).
The device tree offset function is useful for buses, where they want to
locate one of their children. The device tree can be scanned to find the
offset of each child, and that offset can then find the device.

At present only root nodes in the device tree are scanned for devices.
But some devices can have children. For example a SPI bus may have
several children for each of its chip selects.

A device can call this function in its bind() or probe() methods to bind

In U-Boot it is pretty common to number devices from 0 and access them
on the command line using this numbering. While it may come to pass that
we will move away from this numbering, the possibility seems remote at
present.
Given that devices within a uclass will have an implied numbering, it
makes sense to build this into driver model as a core feature. The cost
is fairly small in terms of code and data space.
With each uclass having numbered devices we can ask for SPI port 0 or
serial port 1 and receive a single device.
Devices typically request a sequence number using aliases in the device
tree. These are resolved when the device is probed, to deal with conflicts.
Sequence numbers need not be sequential and holes are permitted.
At present there is no support for sequence numbers using static platform
data. It could easily be added to 'struct driver_info' if needed, but it
seems better to add features as we find a use for them, and the use of -1
to mean 'no sequence' makes the default value somewhat painful.

Driver model currently only operates after relocation is complete. In this
state U-Boot typically has a small amount of memory available. In adding
support for driver model prior to relocation we must try to use as little
memory as possible.
In addition, on some machines the memory has not be inited and/or the CPU
is not running at full speed or the data cache is off. These can reduce
execution performance, so the less initialisation that is done before
relocation the better.
An immediately-obvious improvement is to only initialise drivers which are
actually going to be used before relocation. On many boards the only such
driver is a serial UART, so this provides a very large potential benefit.
Allow drivers to mark themselves as 'pre-reloc' which means that they will
be initialised prior to relocation. This can be done either with a driver
flag or with a 'dm,pre-reloc' device tree property.
To support this, the various dm scanning function now take a 'pre_reloc_only'
parameter which indicates that only drivers marked pre-reloc should be
bound.

Commit 95fac6ab45 "sandbox: Use os functions to read host device tree"
removed the ability for get_device_and_partition() to handle the "host"
device type, and redirect accesses to it to the host filesystem. This
broke some unit tests that use this feature. So, revert that change. The
code added back by this patch is slightly different to pacify checkpatch.
However, we're then left with "host" being both:
- A pseudo device that accesses the hosts real filesystem.
- An emulated block device, which accesses "sectors" inside a file stored
on the host.
In order to resolve this discrepancy, rename the pseudo device from host
to hostfs, and adjust the unit-tests for this change.
The "help sb" output is modified to reflect this rename, and state where
the host and hostfs devices should be used.
