The third test here shows binman's current, inconsistent approach to

cb43ac184f dm: Don't allow U_BOOT_DEVICE() when of-platdata is used
With of-platdata, the devicetree is supposed to specify all the devices
in the system. So far this hasn't really mattered since of-platdata still
works correctly.

However, new of-platdata features rely on numbering the devices in a
particular order so that they can be referenced by a single integer. It is
tricky to implement this efficiently when other devices are present in the
build.

To address this, disable use of U_BOOT_DEVICE() when of-platdata is
enabled. This seems acceptable as it is not supposed to be used at all,
except in SPL/TPL, where of-platdata is the recommended approach.

This breaks one non-compliant boards at present: mx6cuboxi

4e28a259fd imx: mx6cuboxi: Disable thermal driver in SPL
This feature is incompatble with of-platdata since it uses the
U_BOOT_DEVICE() macro. With of-platdata the only devices permitted are
those created by dtoc.

The driver is not used in SPL anyway, so exclude it from that build.

8a38abfc43 dm: Use driver_info index instead of pointer
At present we use a 'node' pointer in the of-platadata phandle_n_arg
structs. This is a pointer to the struct driver_info for a particular
device, and we can use it to obtain the struct udevice pointer itself.

Since we don't know the struct udevice pointer until it is allocated in
memory, we have to fix up the phandle_n_arg.node at runtime. This is
annoying since it requires that SPL's data is writable and adds a small
amount of extra (generated) code in the dm_populate_phandle_data()
function.

Now that we can find a driver_info by its index, it is easier to put the
index in the phandle_n_arg structures.

Update dtoc to do this, add a new device_get_by_driver_info_idx() to look
up a device by drive_info index and update the tests to match.

e41651fffd dm: Support parent devices with of-platdata
At present of-platdata does not provide parent information. But this is
useful for I2C devices, for example, since it allows them to determine
which bus they are on.

Add support for setting the parent correctly, by storing the parent
driver_info index in dtoc and reading this in lists_bind_drivers(). This
needs multiple passes since we must process children after their parents
already have been bound.

a294ead8d2 dm: Use an allocated array for run-time device info
At present we update the driver_info struct with a pointer to the device
that it created (i.e. caused to be bound). This works fine when U-Boot SPL
is stored in read-write memory. But on some platforms, such as Intel
Apollo Lake, it is not possible to update the data memory.

In any case, it is bad form to put this information in a structure that is
in the data region, since it expands the size of the binary.

Create a new driver_rt structure which holds runtime information about
drivers. Update the code to store the device pointer in this instead.
Also update the test check that this works.

b25ff5cbaa dm: test: Add a way to run SPL tests
Add a -u flag for U-Boot SPL which requests that unit tests be run. To
make this work, export dm_test_main() and update it to skip test features
that are not used with of-platdata.

To run the tests:

   $ spl/u-boot-spl -u
   U-Boot SPL 2020.10-rc5 (Oct 01 2020 - 07:35:39 -0600)
   Running 0 driver model tests
   Failures: 0

At present there are no SPL unit tests.

Note that there is one wrinkle with these tests. SPL has limited memory
available for allocation. Also malloc_simple does not free memory
(free() is a nop) and running tests repeatedly causes driver-model to
reinit multiple times and allocate memory. Therefore it is not possible
to run more than a few tests at a time. One solution is to increase the
amount of malloc space in sandbox_spl. This is not a problem for pytest,
since it runs each test individually, so for now this is left as is.

1b27273e09 dtoc: Order the structures internally by name
At present the structures are written in name order, but parents have to
be written before their children, so the file does not end up being in
order. The order of nodes in _valid_nodes matches the order of the
devicetree.

Update the code so that _valid_nodes is in sorted order, by C name of
the structure. This allows us to assign a sequential ordering to each
U_BOOT_DEVICE() declaration.

U-Boot's linker lists are also ordered alphabetically, which means that
the order in the driver_info list will match the order used by dtoc. This
defines an index ('idx') for the U_BOOT_DEVICE declarations. They appear
in alphabetical order, numbered from 0 in _valid_nodes and in the
driver_info linker list.

Add a comment against each declaration, showing the idx value.
