At present the ofnode interface is somewhat limited, in that it cannot
access the device tree provided by the OS, only the one used by U-Boot
itself (assuming these are separate). This prevents using ofnode functions
to handle device tree fixups, i.e. ft_board_setup() and the like.
The ofnode interface was introduced to allow a consistent API to access
the device tree, whether a flat tree or a live tree (OF_LIVE) is in use.
With the flat tree, adding nodes and properties at the start of the tree
(as often happens when writing to the /chosen node) requires copying a
lot of data for each operation. With live tree, such operations are
quite a bit faster, since there is no memory copying required. This has to
be weighed against the required memory allocation with OF_LIVE, as well
as the cost of unflattening and flattening the device tree which U-Boot
is running.
This series enables support for access to multiple device trees with the
ofnode interface. This is already available to some extent with OF_LIVE,
but some of the ofnode functions need changes to allow the tree to be
specified.
The mechanism works by using the top 1-4 bits of the device tree offset.
The sign bit is not affected, since negative values must be supported.
With this implemented, it becomes possible to use the ofnode interface
to do device tree fixups. The only current user is the EVT_FT_FIXUP
event.
This has two main benefits:
- ofnode can now be used everywhere, in preference to the libfdt calls
- live tree can eventually be used everywhere, with potential speed
improvements when larger number of fixups are used
This series is only a step along the way. Firstly, while it is possible
to access the 'fix-up' tree using OF_LIVE, most of the fixup functions use
flat tree directly, rather than the ofnode interface. These need to be
updated. Also the tree must be flattened again before it is passed to the
OS. This is not currently implemented.
With OFNODE_MULTI_TREE disabled this has almost no effect on code size:
around 4 bytes if EVENT is enabled, 0 if not. With the feature enabled,
the increase is around 500 bytes, e.g. on venice2:
buildman -b ofn venice2 -sS --step 0
Summary of 2 commits for 1 boards (1 thread, 64 jobs per thread)
01: image: Drop some other #ifdefs in image-board.c
arm: w+ venice2
23: dm: core: Add the ofnode multi-tree implementation
24: wip
arm: (for 1/1 boards) all +580.0 text +580.0
This size increase is not too bad, considering the extra functionality,
but is too large to enable everywhere. So for now this features needs to
be opt-in only, based on EVENT.

This is not needed and we should avoid typedefs. Use the struct instead.

This function currently assumes that the control FDT is used. Update it
to allow a root node to be passed, so it can work with any tree.
Also add a comment to ofnode_get_by_phandle() so that its purpose is
clear.

Now that we support writing to ofnodes, the const is not accurate. Drop
it to avoid undesirable casting.

When the flat device tree changes it can mess up the live tree since that
uses the flat tree for its strings. This affects only a few sandbox tests
which modify the device tree, but the number will grow as ofnode support
for writing improves.
While the control FDT is not intended to change while U-Boot is running,
some tests do so. For example, the ofnode interface only supports
modifying properties in the control FDT, so tests must use that.
To solve this problem, keep a copy of the FDT and restore it as needed
when the test is finished. The copy only happens on sandbox (except SPL
builds), to reduce memory usage and because these tests are not useful on
other boards. For other boards, a checksum is taken to ensure that nothing
changes.
It would be possible to always checksum the FDT on sandbox and only
restore it if needed, but this is slightly slower than restoring it every
time, at least with crc8.

If the device tree changes during a test and we cannot restore it, mark
it as such so that future tests which need the live tree are skipped.

This was a workaround for a rare situation. Now that it will be more
common and we have a proper fix, drop the flag. We can run both types of
tests in the same sandbox executable, even if the flat device tree is
modified.

At present there is only one device tree used by the ofnode functions,
except for some esoteric use of live tree. In preparation for supporting
more than one, add a way to reset the list of device trees.
For now this does nothing.

The flat device tree is assumed to be the control FDT but this is not
always the case. Update the ofnode implementation to obtain the node via
an function call so we can eventually add support for selecting different
trees.

At present dm_test_ofnode_root() does this manually. Add some inline

When we have multiple trees, the ofnode logic needs to be told which one
to use. Create a new function which takes an oftree argument, along with
a helper to obtain the FDT pointer from an oftree.

In some cases we want to obtain an ofnode in the same tree as a different
ofnode, such as when looking up a subnode. At present this is trivial,
since there is only one tree. When there are multiple trees, this
implementation will change.
Also move the ofnode_to_offset() function up higher in the header file,
since we will need to provide a different implementation with multiple
trees.

At present, unless OF_LIVE is enabled, ofnode only supports access to one
device tree, the control FDT. This is because only the node offset is
encoded in ofnode, with the tree being implicit.
This makes ofnode (without OF_LIVE) unsuitable for device tree fixups, as
implemented by ft_board_setup() and other such functions.
To solve this, we can use the top bits of the node offset to hold a tree
ID.
Add the definitions for this.

Add the logic to redirect requests for the device tree through a function
which can look up the tree ID. This works by using the top bits of
ofnode.of_offset to encode a tree.
It is assumed that there will only be a few device trees used at runtime,
typically the control FDT (always tree ID 0) and possibly a separate FDT
to be passed the OS.
The maximum number of device trees supported at runtime is 8, with this
implementation. That would use bits 30:28 of the node-offset value,
meaning that the positive offset range is limited to bits 27:0, versus
30:1 with this feature disabled. That still allows a device tree of up
to 256MB, which should be enough for most FITs. Larger ones can be
supported by using external data with the FIT, or by enabling OF_LIVE.
Update the documentation a little.

It would be helpful to use livetree for fixups, since adding a lot of nodes and

I'm confused. The documentation comment further down says that len is
the length of name. So why this check? And further, the only caller (at
least introduced here, haven't been through the whole series) indeed
passes strlen(name).
So why is that even a parameter? Can't of_add_subnode() just do
len=strlen(name) itself? And then of course the strlen(name)==len
condition goes away, and the strncmp() can just be spelled strcmp() -
which also looks much more natural when asking "does such a child node
already exist".
> + return -EEXIST;
It seems natural to provide the existing node in *childp when -EEXIST.
Callers that want to error out on -EEXIST can just do that and ignore
that value, but callers that just wants to ensure there is a subnode
with the given name can avoid doing a find_subnode() upfront, which
should make much code much more compact.

Confused. Above, we use parent->name as a condition for whether
parent->full_name exists (or at least whether we should compute its
strlen). Here we unconditionally access parent->full_name. I don't know
the rules for the root node, but I can kind of guess that it has ->name
NULL and ->full_name set to "". Perhaps that could be clarified in the
documentation for struct device_node?
And if I'm right, that means there's no point asking if parent->name is
NULL or not; strlen(parent->full_name) gives the right answer regardless.
