930a3ddade dm: core: Support accessing core tags
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.

d8318feba1 patman: test_util: Use unittest text runner to print test results
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.

43ba492670 dtoc: Detect drivers which do not parse correctly
At present if a driver is missing a uclass or compatible stirng, this
is silently ignored. This makes sense in most cases, particularly for

But it is also not very helpful. When there is some sort of problem

cause.

170732523b dtoc: Correct dtoc output when testing
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.

f6176651bc dtoc: Support adding subnodes alongside existing ones
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.

71719e15e8 dtoc: Tweak ordering of fdt-offsets refreshing
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.
