At present this function adds up the total size of entries to work out the
size of a section's contents. With compression this is no-longer enough.
We may as well bite the bullet and build the section contents instead.
Call _BuildSectionData() to get the (possibly compressed) contents and
GetPaddedData() to get the same but with padding added.
Note that this is inefficient since the section contents is calculated
twice. Future work will improve this.
This affects testPackOverlapMap() since the error is reported with a
different section size now (enough to hold the contents). Update that at
the same time.

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.

Create a new _BuildSectionData() to hold the code that is now in

Unfortunately this breaks the testDual test. Rather than squash several

When reading subentries of each image, the FIT entry type directly
concatenates their contents without padding them according to their
offset, size, align, align-size, align-end, pad-before, pad-after
properties.
This patch makes sure these properties are respected by offloading this
image-data building to the section etype, where each subnode of the
"images" node is processed as a section. Alignments and offsets are
respective to the beginning of each image. For example, the following
fragment can end up having "u-boot-spl" start at 0x88 within the final
FIT binary, while "u-boot" would then end up starting at e.g. 0x20088.
fit {
description = "example";
images {
kernel-1 {
description = "U-Boot with SPL";
type = "kernel";
arch = "arm64";
os = "linux";
compression = "none";
u-boot-spl {
};
u-boot {
align = <0x10000>;
};
};
};

FIT (Flat Image Tree) is the main image format used by U-Boot. In some
cases scripts are used to create FITs within the U-Boot build system. This
is not ideal for various reasons:
- Each architecture has its own slightly different script
- There are no tests
- Some are written in shell, some in Python
To help address this, add support for FIT generation to binman. This works
by putting the FIT source directly in the binman definition, with the
ability to adjust parameters, etc. The contents of each FIT image come
from sub-entries of the image, as is normal with binman.

A recent change adjusted the symbol calculation to work on x86 but broke
it for Tegra. In fact this is because they have different needs.
On x86 devices the code is linked to a ROM address and the end-at-4gb
property is used for the image. In this case there is no need to add the
base address of the image, since the base address is already built into
the offset and image-pos properties.
On other devices we must add the base address since the offsets start at
zero.
In addition the base address is currently added to the 'offset' and 'size'
values. It should in fact only be added to 'image-pos', since 'offset' is
relative to its parent and 'size' is not actually an address. This code
should have been adjusted when support for 'image-pos' and 'size' was
added, but it was not.
To correct these problems:
- move the code that handles adding the base address to section.py, which
can check the end-at-4gb property and which property
(offset/size/image-pos) is being read
- add the base address only when needed (only for image-pos and not if the
image uses end-at-4gb)
- add a note to the documentation
- add a separate test to cover x86 behaviour
