2090f1e3d0 binman: Allow symbols to be resolved inside sections
At present we only support symbols inside binaries which are at the top
level of an image. This restrictions seems unreasonable since more complex
images may want to group binaries within different sections.

Relax the restriction, adding a new _SetupTplElf() helper function.

Also fix a typo in the comment for testTpl().

1542c8b5fc binman: Use the Makefile for u_boot_binman_syms
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.

53e22bf38c binman: Use the Makefile to build ELF test files
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.

5e239183f6 binman: x86: Separate out 16-bit reset and init code
At present these two sections of code are linked together into a single
2KB chunk in a single file. Some Intel SoCs like to have a FIT (Firmware
Interface Table) in the ROM and the pointer for this needs to go at
0xffffffc0 which is in the middle of these two sections.

include just the 16-bit data.

2250ee6ee6 binman: Add support for an x86 'reset' section
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.

eb0f4a4cb4 binman: Support replacing data in a cbfs
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.

61ec04f9ed binman: Support shrinking a entry after packing
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

51014aabc2 binman: Allow updating entries that change size
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.

a004f29464 binman: Tidy up _SetupDtb() to use its own temporary file
At present EnsureCompiled() uses an file from the 'output' directory (in
the tools module) when compiling the device tree. This is fine in most
cases, allowing useful inspection of the output files from binman.

However in functional tests, _SetupDtb() creates an output directory and
immediately removes it afterwards. This serves no benefit and just
confuses things, since the 'official' output directory is supposed to be
created and destroyed in control.Binman().

Add a new parameter for the optional temporary directory to use, and use a
separate temporary directory in _SetupDtb().

8beb11ea6e binman: Convert Image to a subclass of Entry
When support for sections (and thus hierarchical images) was added to
binman, the decision was made to create a new Section class which could
be used by both Image and an Entry_section class. The decision between
using inheritance and composition was tricky to make, but in the end it
was decided that Image was different enough from Entry that it made sense
to put the implementation of sections in an entirely separate class. It
also has the advantage that core Image code does have to rely on an entry
class in the etype directory.

This work was mostly completed in commit:

   8f1da50ccc "binman: Refactor much of the image code into 'section'

As a result of this, the Section class has its own version of things like
offset and size and these must be kept in sync with the parent
Entry_section class in some cases.

In the last year it has become apparent that the cost of keeping things in
sync is larger than expected, since more and more code wants to access
these properties.

An alternative approach, previously considered and rejected, now seems
better.

Adjust Image to be a subclass of Entry_section. Move the code from Section
(in bsection.py) to Entry_section and delete Section. Update all tests
accordingly.

This requires substantial changes to Image. Overall the changes reduce
code size by about 240 lines. While much of that is just boilerplate from
Section, there are quite a few functions in Entry_section which now do not
need to be overiden from Entry. This suggests the change is beneficial
even without further functionality being added.

A side benefit is that the properties of sections are now consistent with
other entries. This fixes a problem in testListCmd() where some properties
are missing for sections.

Unfortunately this is a very large commit since it is not feasible to do
the migration piecemeal. Given the substantial tests available and the
100% code coverage of binman, we should be able to do this safely.

The method of multiplying a character by a number works well for creating

3ab9598df7 binman: Rename 'position' to 'offset'
After some thought, I believe there is an unfortunate naming flaw in
binman. Entries have a position and size, but now that we support
hierarchical sections it is unclear whether a position should be an
absolute position within the image, or a relative position within its
parent section.

At present 'position' actually means the relative position. This indicates
a need for an 'image position' for code that wants to find the location of
an entry without having to do calculations back through parents to
discover this image position.

A better name for the current 'position' or 'pos' is 'offset'. It is not
always an absolute position, but it is always an offset from its parent
offset.

It is unfortunate to rename this concept now, 18 months after binman was
introduced. However I believe it is the right thing to do. The impact is
mostly limited to binman itself and a few changes to in-tree users to
binman:

   tegra
   sunxi
   x86

The change makes old binman definitions (e.g. downstream or out-of-tree)
incompatible if they use the 'pos = <...>' property. Later work will
adjust binman to generate an error when it is used.

Use the name 'bsection' for the module so we can use 'section' for the
etype module.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

3759df0c08 tools: Update python "help" tests to cope with "more" oddities
In some cases when "more" is told to page a given file it will prepend
the output with:
::::::::::::::
/PATH/TO/THE/FILE
::::::::::::::

And when this happens the output will not match the expected length.
Further, if we use a different pager we will instead fail the coverage
tests as we will not have 100% coverage.  Update the help test to remove
the string in question.

1979063264 binman: Support accessing binman tables at run time
Binman construct images consisting of multiple binary files. These files
sometimes need to know (at run timme) where their peers are located. For
example, SPL may want to know where U-Boot is located in the image, so
that it can jump to U-Boot correctly on boot.

In general the positions where the binaries end up after binman has
finished packing them cannot be known at compile time. One reason for
this is that binman does not know the size of the binaries until
everything is compiled, linked and converted to binaries with objcopy.

To make this work, we add a feature to binman which checks each binary
for symbol names starting with '_binman'. These are then decoded to figure
out which entry and property they refer to. Then binman writes the value
of this symbol into the appropriate binary. With this, the symbol will
have the correct value at run time.

Macros are used to make this easier to use. As an example, this declares
a symbol that will access the 'u-boot-spl' entry to find the 'pos' value
(i.e. the position of SPL in the image):

   binman_sym_declare(unsigned long, u_boot_spl, pos);

This converts to a symbol called '_binman_u_boot_spl_prop_pos' in any
binary that includes it. Binman then updates the value in that binary,
ensuring that it can be accessed at runtime with:

   ulong u_boot_pos = binman_sym(ulong, u_boot_spl, pos);

This assigns the variable u_boot_pos to the position of SPL in the image.

f689890d8e binman: Adjust size of test SPL binary
This is only 3 bytes long which is not enough to hold two symbol values,

Using very small regions is useful since we can easily compare them in
tests and errors are fairly easy to diagnose.

b50e5611a6 binman: Add a function to read ELF symbols
In some cases we need to read symbols from U-Boot. At present we have a
a few cases which does this via 'nm' and 'grep'.

It is better to use objdump since that tells us the size of the symbols
and also whether it is weak or not.

Add a new module which reads ELF information from files. Update existing
uses of 'nm' to use this module.
