It is useful to write the position and size of each entry back to the
device tree so that U-Boot can access this at runtime. Add a feature to
support this, along with associated tests.

Once binman has packed the image, the position and size of each entry is
known. It is then possible for binman to update the device tree with these
positions. Since placeholder values have been added, this does not affect
the size of the device tree and therefore the packing does not need to be
performed again.
Add a new SetCalculatedProperties method to handle this.

Some entry types modify the device tree, e.g. to remove microcode or add a
property. So far this just modifies their local copy and does not affect
a 'shared' device tree.
Rather than doing this modification in the ObtainContents() method, and a
new ProcessFdt() method which is specifically designed to modify this
shared device tree.
Move the existing device-tree code over to use this method, reducing
ObtainContents() to the goal of just obtaining the contents without any
processing, even for device tree.

At present only some of the fdt functionality is tested. Add more tests to

At present the Fdt class has its own copy of the device tree. This is
confusing an unnecessary now that pylibfdt has its own. Drop it and
provide access functions to the buffer.
This allows us to move the rest of the implementation to use pylibfdt
methods instead of directly calling libfdt stubs.
Signed-off-by: Simon Glass <sjg@chromium.org>
Now that pylibfdt supports a fuller API we don't need to directly call
the libfdt stubs. Update the code to use the Fdt methods instead.
Some other cases remain which will be tidied up in a later commit, since
they need larger changes.

When a test fails due to an output mismatch (e.g. due to a new property
being adding to a test file) it is currently hard to update the test to
the new output. In particular the tabs in the file are written as \t in
the Python tests.
To make this easier, write both the expected and actual results to /tmp
to allow use of meld, and copying into the test.

At present this module is tested via the dtoc tests. This is a bit painful
since the tests are at a higher level and so failures are more difficult

This provides various patches sent to the devicetree-compiler mailing list
to enhance the Python bindings. A final version of this patch may be
created once upstreaming is complete, but if it takes too long, this can
act as a placeholder.
New pylibfdt features:
- Support for most remaining, relevant libfdt functions
- Support for sequential-write functions

At present the contents of an entry are set in subclasses simply by
assigning to the data and content_size properties. Add some methods to do
this, so that we have more control. In particular, add a method to set the
contents without changing its size, so we can validate that case.
Add a test case for trying to change the size when this is not allowed.

This method is supposed to return the contents of an entry. However at
present there is no check that it actually does. Also some implementations
do not return 'True' to indicate success, as required.
Add a check for things working as expected, and correct the
implementations.
This requires some additional test cases to cover things which were missed
originally. Add these at the same time.

At present we call the three entries first, second and third. Rename them

Signed-off-by: Simon Glass <sjg@chromium.org>
This fake entry is used for testing. At present it only has one behaviour
which is to return an invalid set of entry positions, to cause an error.
The fake entry will need to be used for other things too. Allow the test
.dts file to specify the behaviour of the fake entry, so we can control
its behaviour easily.
While we are here, drop the ReadContents() method, since this only applies
to subclasses of Entry_blob, which Entry__testing is not.

Support a default memory bank, specified in reg, as well as

This allows memory information to be provided in the device tree,

similar devices with different memory banks, as the board-id values
or masks can be used to match devices.

On the A64 the clock for the first USB controller is actually the parent
of the clock for the second controller, so turning them off in that order
makes the system hang.
Fix this by only turning off *both* clocks when the *last* OHCI controller
is brought down. This covers the case when only one controller is used.

The Allwinner A64 SoCs suffers from an arch timer implementation erratum,
where sometimes the lower 11 bits of the counter value erroneously
become all 0's or all 1's [1]. This leads to sudden jumps, both forwards and
backwards, with the latter one often showing weird behaviour.
Port the workaround proposed for Linux to U-Boot and activate it for all
A64 boards.
This fixes crashes when accessing MMC devices (SD cards), caused by a
recent change to actually use the counter value for timeout checks.
