Remove this file from git and instead build it using the Makefile.
With this change a few things need to be adjusted:
1. The 'notes' section no-longer appears at the start of the ELF file
(before the code), so update testSymbols to adjust the offsets.
2. The dynamic linker is disabled to avoid errors like:
"Not enough room for program headers, try linking with -N"
3. The interpreter note is moved to the end of the image, so that the
binman symbols appear first.

Remove this file from git and instead build it using the Makefile.
Update tools.GetInputFilename() to support reading files from an absolute
path, so that we can read the Elf test files easily. Also make sure that
the temp directory is report in ELF tests as this was commented out.

At present the ELF test files are checked into the U-Boot tree. This is
covenient since the files never change and can be used on non-x86
platforms. However it is not good practice to check in binaries and in
this case it does not seem essential.
Update the binman test-file Makefile to support having source in a
different directory. Adjust binman to run it to build bss_data, as a
start. We can add other files as needed.

A Firmware Image Table (FIT) is a data structure defined by Intel which
contains information about various things needed by the SoC, such as
microcode.
Add support for this entry as well as the pointer to it. The contents of
FIT are fixed at present. Future work is needed to support adding
microcode, etc.

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.

At present the Intel IFWI entry uses 'replace' without the 'ifwi-' prefix.
This is a fairly generic name which might conflict with the main Entry
base class at some point, if more features are added. Add a prefix.

Add a 'replace' command to binman to permit entries to be replaced, either
individually or all at once (using a filter).

At present binman cannot replace data within a CBFS since it does not
allow rewriting of the files in that CBFS. Implement this by using the
new WriteData() method to handle the case.
Add a header to compressed data so that the amount of compressed data can
be determined without reference to the size of the containing entry. This
allows the entry to be larger that the contents, without causing errors in
decompression. This is necessary to cope with a compressed device tree
being updated in such a way that it shrinks after the entry size is
already set (an obscure case). It is not used with CBFS since it has its
own metadata for this. Increase the number of passes allowed to resolve
the position of entries, to handle this case.
Add a test for this new logic.

The Intel descriptor must always appear at the start of an (x86) image,
so it is supposed to position itself there always. However there is no
explicit test for this. Add one and fix a bug introduced by the recent
change to adjust Entry to read the node in a separate call.

Sometimes an entry may shrink after it has already been packed. In that
case we must repack the items. Of course it is always possible to just
leave the entry at its original size and waste space at the end. This is
what binman does by default, since there is the possibility of the entry
changing size every time binman calculates its contents, thus causing a
loop.

So far we don't allow entries to change size when repacking. But this is
not very useful since it is common for entries to change size after an
updated binary is built, etc.
Add support for this, respecting the original offset/size/alignment
constraints of the image layout. For this to work the original image
must have been created with the 'allow-repack' property.
This does not support entry types with sub-entries such as files and
CBFS, but it does support sections.

The positioning does not currently work correctly if at the end of an
image with no fixed size. Also if the header is in the middle of an image
it can cause a gap in the image since the header position is normally at
the image end, so entries after it are placed after the end of the image.
Fix these problems and add more tests to cover these cases.

At present it is not possible to discover the contraints to repacking an
image (e.g. maximum section size) since this information is not preserved
from the original image description.
Add new 'orig-offset' and 'orig-size' properties to hold this. Add them to
the main device tree in the image.

While it is useful and efficient to build images in a single pass from a
unified description, it is sometimes desirable to update the image later.
Add support for replace an existing file with one of the same size. This
avoids needing to repack the file. Support for more advanced updates will
come in future patches.

Current test coverage is likely sufficient for the logic used to place
sections in the image. However it seems useful to add a test specifically
for nested sections, since these could have some unusual interactions.
Add a new test for this and aligned sections. This test failed before the
refactor to drop the bsection.py file (Section class), but passes now.

It is useful to be able to quickly locate the FDT map in the image. An
easy way to do this is with a pointer at the start or end of the image.
Add an 'image header' entry, which places a magic number followed by a
pointer to the FDT map. This can be located at the start or end of the
image, or at a chosen location.
As part of this, update GetSiblingImagePos() to detect missing siblings.

An FDT map is an entry which holds a full description of the image
entries, in FDT format. It can be discovered using the magic string at
its start. Tools can locate and read this entry to find out what entries
are in the image and where each entry is located.

A feature of CBFS is that it allows files to be positioned at particular
offset (as with binman in general). This is useful to support
execute-in-place (XIP) code, since this may not be relocatable.

Normally x86 platforms use the end-at-4gb option. This currently produces
an FMAP with positions which have a large offset. The use of end-at-4gb is
a useful convenience within binman, but we don't really want to export
a map with these offsets.
Fix this by subtracting the 'skip at start' parameter.
Also put the code which convers names to fmap format, for clarity.

Binman currently supports updating the main device tree with things like
the position of each entry. Extend this support to SPL and TPL as well,
since they may need (a subset of) this information.
Also adjust DTB output files to have a .out extension since this seems
clearer than having a .dtb extension with 'out' in the name somwhere.
Also add a few missing comments and update the DT setup code to use
ReadFile and WriteFile().

Currently binman calculates '_skip_at_start' based on 'end-at-4gb'
property and it is used for x86 images.
For PowerPC mpc85xx based CPU, CONFIG_SYS_TEXT_BASE is the entry
offset of the first entry. It can be 0xeff40000 or 0xfff40000 for
nor flash boot, 0x201000 for sd boot etc, so "_skip_at_start"
should be set to CONFIG_SYS_TEXT_BASE.
'end-at-4gb' property is not applicable where CONFIG_SYS_TEXT_BASE +
Image size != 4gb.
Add new property 'skip-at-start' in Section class so that
'_skip_at_start' can be calculated either based on 'end-at-4gb'
or based on "skip-at-start".
Add a test case to check that 'skip-at-start' and 'end-at-4gb'
property can't be used together.
