At present tag numbers are only allocated for non-core data, meaning that
the 'core' data, like priv and plat, are accessed through dedicated
functions.
For debugging and consistency it is convenient to use tags for this 'core'
data too. Add support for this, with new tag numbers and functions to
access the pointer and size for each.
Update one of the test drivers so that the uclass-private data can be
tested here.
There is some code duplication with functions like device_alloc_priv() but
this is not addressed for now. At some point, some rationalisation may
help to reduce code size, but more thought it needed on that.

At present this driver uses 'priv' struct to hold 'plat' data, which is
confusing. The contents of the strct don't matter, since only dtoc is
using it. Create a new struct with the correct name.

The python tools' test utilities handle printing test results, but the
output is quite bare compared to an ordinary unittest run. Delegate
printing the results to a unittest text runner, which gives us niceties
like clear separation between each test's result and how long it took to
run the test suite.
Unfortunately it does not print info for skipped tests by default, but
this can be handled later by a custom test result subclass. It also does
not print the tool name; manually print a heading that includes the
toolname so that the outputs of each tool's tests are distinguishable in
the CI output.

It is helpful to support a string or stringlist containing a list of
space-separated arguments, for example:
args = "-n fred", "-a", "123";
This resolves to the list:
-n fred -a 123
which can be passed to a program as arguments.
Add a helper to do the required processing.

This does not work at present, since the current algorithm assumes that
either there are no nodes or all nodes have an offset. If a node is new,
but an old node is still in the tree, then syncing fails due to this

At present if we see 'ranges' property (with no value) we assume it is a
boolean, as per the devicetree spec.
But another node may define 'ranges' with a value, forcing us to widen it
to an int array. At present this is not supported and causes an error.

At present if a driver is missing a uclass or compatible stirng, this
is silently ignored. This makes sense in most cases, particularly for
the compatible string, since it is not required except when the driver
is used with of-platdata.
But it is also not very helpful. When there is some sort of problem
with a driver, the missing compatible string (for example) may be the
cause.
Add a warning in this case, showing it only for drivers which are used
by the build.

At present we show when a driver is missing but this is not always that
useful. There are various reasons why a driver may appear to be missing,
such as a parse error in the source code or a missing field in the driver
declaration.
Update the implementation to record all warnings for each driver, showing
only those which relate to drivers that are actually used. This avoids
spamming the user with warnings related to a driver for a different board.

With of-platdata-inst we want to set up a reference to each devices'
parent device, if there is one. If we find that the device has a parent
(i.e. is not a root node) but it is not in the list of devices being
written, then we cannot create the reference.
Report an error in this case, since it indicates that the parent node
is either missing a compatible string, is disabled, or perhaps does not
have any properties because it was not tagged for SPL.

At present each invocation of run_steps() updates OUTPUT_FILES_COMMON,
since it does not make a copy of the dict. This is fine for a single
invocation, but for tests, run_steps() is invoked many times.
As a result it may include unwanted items from the previous run, if it
happens that a test runs twice on the same CPU. The problem has not been
noticied previously, as there are few enough tests and enough CPUs that
is is rare for the 'wrong' combination of tests to run together.
Fix this by making a copy of the dict, before updating it. Update the
tests to suit, taking account of the files that are no-longer generated.
With this fix, we no-longer generate files which are not needed for a
particular state of OF_PLATDATA_INST, so the check_instantiate() function
is not needed anymore. It has become dead code and so fails the
code-coverage test (dtoc -T). Remove it.

This existing code assumes that a reg property is larger than one cell,
but this is not always the case. Fix this assumption.
Also if a node's parent is missing the #address-cells and #size-cells
properties we use 2 as a default for each. But this should not happen in
practice. More likely the properties were removed for SPL due to there
being no 'u-boot,dm-pre-reloc' property, or similar. Add a warning for
this as the failure can be very confusing.

So far we have only needed to add subnodes to empty notds, so have not
had to deal with ordering. However this feature is needed for binman's
expanded nodes, since there may be another node in the same section.
While libfdt adds new properties after existing properties, it adds new
subnodes before existing subnodes. This means that we must reorder the
nodes in the cached version, so that the ordering remains consistent.
Update the sync implementation to sync existing subnodes first, then
add new ones, then tidy up the ordering in the cached version. Update the
test to cover this behaviour.
Also improve the comment about property syncing while we are here.

Add a new test that adds a subnode alongside an existing one, as well as
adding properties to a subnode. This will expand to adding multiple
subnodes in future patches. Put a node after the one we are adding to so
we can check that things sync correctly.
The testAddNode() test should be in the TestNode class since it is a node
test, so move it.

Once the tree has been synced, thus potentially moving things around in the
fdt, we set _cached_offsets to False so that a refresh will happen next
time a property is accessed.
This 'lazy' refresh doesn't really save much time, since refresh is a very
fast operation, just a single walk of the tree. Also, having the refresh
happen in the bowels of property access it makes it harder to figure out
what is going on.
Simplify the code by always doing a refresh before and after a sync. Set
_cached_offsets to True immediately after this, in the Refresh() function,
since this makes more sense than doing it in the caller.
