At present ofnode_write_prop() is inconsistent between livetree and
flattree, in that livetree requires the caller to ensure the property
value is stable (e.g. in rodata or allocated) but flattree does not, since
it makes a copy.
This makes the API call a bit painful to use, since the caller must do
different things depending on OF_LIVE.
Add a new 'copy' argument which tells the function to make a copy if
needed. Add some tests to cover this behaviour.

There is a still more testing needed for the failure cases, since at

We need to be able to look up phandles in any FDT, not just the control
FDT. Use the 'other' FDT to test this, with a helper function which gets

This function turns out to be a little confusing since it looks up a path
and also registers the tree. Split it into two, one that gets the root
node and one that looks up a path, so the purpose is clear.
Registering the tree will happen in a function to be added in a later
patch, called oftree_from_fdt().

At present the sandbox timer uses localtime() which can jump around twice
a year when daylight-saving time changes.
It would be tricky to make use of gmtime() since we still need to present
the time in local time, as seems to be required by U-Boot's RTC interface.
The problem can only happen once, so use a loop to detect it and try
again. This should be sufficient to detect either a change in the 'second'
value, or a daylight-saving change. We can assume that the latter also
incorporates a 'second' change, so there is no need to loop more than
twice.

In generally it is not permitted to implement an ofnode function only for
flat tree or live tree. Both must be supported. Also the code for

At present ofnode only works with a single device tree, for the most part.
This is the control FDT used by U-Boot.
When booting an OS we may obtain a different device tree and want to
modify it. Add some initial support for this into the ofnode API.
Note that we don't permit aliases in this other device tree, since the
of_access implementation maintains a list of aliases collected at
start-up. Also, we don't need aliases to do fixups in the other FDT. So
make sure that flat tree and live tree processing are consistent in this
area.

A common external watchdog circuit is kept alive by triggering a short
pulse on the reset pin. This patch adds support for this use case, while
making the algorithm configurable in the devicetree.
The "linux,wdt-gpio" driver being modified is based off the equivalent
driver in the Linux kernel, which provides support for this algorithm.
This patch brings parity to this driver, and is kept aligned with
the functionality and devicetree configuration in the kernel.
It should be noted that this adds a required property named 'hw_algo'
to the devicetree binding, following suit with the kernel. I'm happy to
make this backward-compatible if preferred.
