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>;
};
};
};
}

Other relevant properties (pad-after, offset, size, align, align-size,
align-end) already work since Pack() sets correct ranges for subentries'
data (.offset, .size variables), but some padding here is necessary to
align the data within this range to match the pad-before property.

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

Entries which include a section and need to obtain its contents call
GetData(), as with any other entry. But the current implementation of this
method in entry_Section requires the size of the section to be known. If
it is unknown, an error is produced, since size is None:
TypeError: can't multiply sequence by non-int of type 'NoneType'
There is no need to know the size in advance since the code can be
adjusted to build up the section piece by piece, instead of patching each
entry into an existing bytearray.
Update the code to handle this and add a test.

At present binman has a single entry type for the 16-bit code code needed
to start up an x86 processor. This entry is intended to include both the
reset vector itself as well as the code to move to 32-bit mode.
However this is not very flexible since in some cases other data needs to
be included at the top of the SPI flash, in between these two pieces. For
example Intel requires that a FIT (Firmware Image Table) pointer be placed
0x40 bytes before the end of the ROM.
To deal with this, add a new reset entry for just the reset vector. A
subsequent change will adjust the existing 'start16' entry.
