When a section is compressed, all entries within it are grouped together
into a compressed block of data. This obscures the start of each
individual child entry.
Avoid reporting bogus 'image-pos' properties in this case, since it is
not possible to access the entry at the location provided. The entire
section must be decompressed first.
CBFS does not support compressing whole sections, only individual files,
so needs no special handling here.

Section contents is not set up when ObtainContents() is called, since
packing often changes the layout of the contents. Ensure that the contents
are correctly recorded by making this function regenerate the section. It
is normally only called by the parent section (when packing) or by the
top-level image code, when writing out the image. So the performance
impact is fairly small.
Now that sections have their contents in their 'data' property, update
testSkipAtStartSectionPad() to check it.

At present padding of sections is inconsistent with other entry types, in
that different pad bytes are used.
When a normal entry is padded by its parent, the parent's pad byte is
used. But for sections, the section's pad byte is used.
Adjust logic to always do this the same way.
Note there is still a special case in entry_Section.GetPaddedData() where
an image is padded with the pad byte of the top-level section. This is
necessary since otherwise there would be no way to set the pad byte of
the image, without adding a top-level section to every image.

Each section is padded up to its size, if the contents are not large
enough. Move this logic from _BuildSectionData() to
GetPaddedDataForEntry() so that all the padding is in one place.

At present this function does the padding needed around an entry. It is

Create a new _BuildSectionData() to hold the code that is now in
GetData(), so that it is clearly separated from entry.GetData() base
function.
Separate out the 'pad-before' processing to make this easier to
understand.
Unfortunately this breaks the testDual test. Rather than squash several
patches into an un-reviewable glob, disable the test for now.
This also affects testSkipAtStartSectionPad(), although it still not
quite what it should be. Update that temporarily for now.

At present we use 'compress' as the property to set the compression of
a 'files' entry. But this conflicts with the same property for entries,
of which Entry_section is a subclass.
Strictly speaking, since Entry_files is in fact a subclass of
Entry_section, the files can be compressed individually but also the
section (that contains all the files) can itself be compressed. With this
change, it is possible to express that.

With of-platdata, the devicetree is supposed to specify all the devices
in the system. So far this hasn't really mattered since of-platdata still
works correctly.
However, new of-platdata features rely on numbering the devices in a
particular order so that they can be referenced by a single integer. It is
tricky to implement this efficiently when other devices are present in the
build.
To address this, disable use of U_BOOT_DEVICE() when of-platdata is
enabled. This seems acceptable as it is not supposed to be used at all,
except in SPL/TPL, where of-platdata is the recommended approach.
This breaks one non-compliant boards at present: mx6cuboxi

At present we use a 'node' pointer in the of-platadata phandle_n_arg
structs. This is a pointer to the struct driver_info for a particular
device, and we can use it to obtain the struct udevice pointer itself.
Since we don't know the struct udevice pointer until it is allocated in
memory, we have to fix up the phandle_n_arg.node at runtime. This is
annoying since it requires that SPL's data is writable and adds a small
amount of extra (generated) code in the dm_populate_phandle_data()
function.
Now that we can find a driver_info by its index, it is easier to put the
index in the phandle_n_arg structures.
Update dtoc to do this, add a new device_get_by_driver_info_idx() to look
up a device by drive_info index and update the tests to match.

At present of-platdata does not provide parent information. But this is
useful for I2C devices, for example, since it allows them to determine

Add support for setting the parent correctly, by storing the parent

needs multiple passes since we must process children after their parents
already have been bound.

At present we update the driver_info struct with a pointer to the device
that it created (i.e. caused to be bound). This works fine when U-Boot SPL
is stored in read-write memory. But on some platforms, such as Intel
Apollo Lake, it is not possible to update the data memory.
In any case, it is bad form to put this information in a structure that is
in the data region, since it expands the size of the binary.
Create a new driver_rt structure which holds runtime information about
drivers. Update the code to store the device pointer in this instead.
Also update the test check that this works.

Failures: 0
At present there are no SPL unit tests.
Note that there is one wrinkle with these tests. SPL has limited memory
available for allocation. Also malloc_simple does not free memory
(free() is a nop) and running tests repeatedly causes driver-model to
reinit multiple times and allocate memory. Therefore it is not possible
to run more than a few tests at a time. One solution is to increase the
amount of malloc space in sandbox_spl. This is not a problem for pytest,
since it runs each test individually, so for now this is left as is.

At present the structures are written in name order, but parents have to

Update the code so that _valid_nodes is in sorted order, by C name of
the structure. This allows us to assign a sequential ordering to each
U_BOOT_DEVICE() declaration.
U-Boot's linker lists are also ordered alphabetically, which means that
the order in the driver_info list will match the order used by dtoc. This
defines an index ('idx') for the U_BOOT_DEVICE declarations. They appear
in alphabetical order, numbered from 0 in _valid_nodes and in the
driver_info linker list.
