0b6023ee41 binman: Plumb expanded entries through fully
Add support for this feature in the control, image and section modules, so
that expanded entries will be selected by default. So far there are no
expanded entry types, so this is a nop.

63aeaeb463 binman: Allow a way to select expanded entries
Add a new command-line option to disable expanded entries. This is needed
for most tests, since it is much easier to 'factor out' this function into
a separate test and keep the existing packing tests simple.

Add the option and select it by default from tests.

5187b80617 binman: Use standard filenames for SPL/TPL devicetree
At present, before any entry expansion is done (such as a 'files' entry
expanding out to individual entries for each file it contains), we check
the binman definition (i.e. '/binman' node) to find out what devicetree
files are used in the images.

This is a pain, since the definition may change during expansion. For
example if there is no u-boot-spl-dtb entry in the definition at the start,
we assume that the SPL devicetree is not used. But if an entry later
expands to include this, then we don't notice.

In fact the flexibility provided by the current approach of checking the
definition is not really useful. We know that we can have SPL and TPL
devicetrees. We know the pathname to each, so we can simply check if the
files are present. If they are present, we can prepare them and update
them regardless of whether they are actually used. If they are not present,
we cannot prepare/update them anyway, i.e. an error will be generated.

Simplify state.Prepare() so it uses a hard-coded list of devicetree files.

Note that state.PrepareFromLoadedData() is left untouched, since in that
case we have a complete definition from the loaded file, but cannot of
course rely on the devicetree files that created it still being present.
So in that case we still check the image defitions.

At present we store an entry as the third field in output_fdt_info[].

7697170e78 binman: Use the fake SPL/TPL only if requested
At present we always use the main devicetree for SPL/TPL as well when
setting up the state. But this it not needed if there is a real devicetree
for SPL or TPL. In fact it confuses things since we cannot distinguish
between one being provided and using the fake one.

Update the code to create the fakes only when requested. Put the mapping
in a constant so we can use it elsewhere.

Rename 'other_fname' to 'fname' while we are here since there is nothing
'other' about it.

939d1062d0 binman: Support reading an image with entry args
Normally when an entry is created, any entry arguments it has are required
to be provided, so it can actually generate its contents correctly.

However when an existing image is read, Entry objects are created for each
of the entries in the image. This happens as part of the process of
reading the image into binman.

In this case we don't need the entry arguments, since we do not intend to
regenerate the entries, or at least not unless requested. So there is no
sense in reporting an error for missing entry arguments.

Add a new property for the Image to handle this case. Update the error
reporting to be conditional on this property.

0ff83da634 binman: Use the actual contents in CheckSize()
At present this function adds up the total size of entries to work out the

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.

different section size now (enough to hold the contents). Update that at

section must be decompressed first.

packing often changes the layout of the contents. Ensure that the contents

impact is fairly small.

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

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.

e72a6be4fc sunxi: binman: Add support for including SCP firmware
Allwinner sun50i SoCs contain an OpenRISC 1000 CPU that functions as a
System Control Processor, or SCP. ARM Trusted Firmware (ATF)
communicates with the SCP over SCPI to implement the PSCI system
suspend, shutdown and reset functionality. Currently, SCP firmware is
optional; the system will boot and run without it, but system suspend
will be unavailable.

Since all communication with the SCP is mediated by ATF, the only thing
U-Boot needs to do is load the firmware into SRAM. The SCP firmware
occupies the last 16KiB of SRAM A2, immediately following ATF.

68158d59d2 sunxi: binman: Update FIT component descriptions
Since commit d879616e9e ("spl: fit: simplify logic for FDT loading for
non-OS boots"), the SPL looks at the "os" properties of FIT images to
determine where to append the FDT.

The "os" property of the "firmware" image also determines how to execute
the next stage of the boot process, as in 1d3790905d ("spl: atf:
introduce spl_invoke_atf and make bl31_entry private"). For this reason,
the next stage must be specified in "firmware", not in "loadables".

To support this additional functionality, and to properly model the boot
process, where ATF runs before U-Boot, add the "os" properties and swap
the firmware/loadable images in the FIT image.

Since this description was copied as an example in commit 70248d6a2916
("binman: Support generating FITs with multiple dtbs"), update those
examples as well for correctness and consistency.

Due to an extra level of indentation, the "data" property containing the

This caused the generated FIT image to be invalid.

1e4687aa47 binman: Use target-specific tools when cross-compiling
Currently, binman always runs the compile tools like cc, objcopy, strip,
etc. using their literal name. Instead, this patch makes it use the
target-specific versions by default, derived from the tool-specific
environment variables (CC, OBJCOPY, STRIP, etc.) or from the
CROSS_COMPILE environment variable.

For example, the u-boot-elf etype directly uses 'strip'. Trying to run
the tests with 'CROSS_COMPILE=i686-linux-gnu- binman test' on an arm64
host results in the '097_elf_strip.dts' test to fail as the arm64
version of 'strip' can't understand the format of the x86 ELF file.

This also adjusts some command.Output() calls that caused test errors or
failures to use the target versions of the tools they call. After this,
patch, an arm64 host can run all tests with no errors or failures using
a correct CROSS_COMPILE value.

5ac7687827 binman: Support cross-compiling test files to x86
These test files are currently "intended for use on x86 hosts", but most
of the tests using them can still pass when cross-compiled to x86 on an
arm64 host.

This patch enables non-x86 hosts to run the tests by specifying a
cross-compiler via CROSS_COMPILE. The list of variables it sets is taken
from the top-level Makefile. It would be possible to automatically set
an x86 cross-compiler with a few blocks like:

    ifneq ($(shell i386-linux-gnu-gcc --version 2> /dev/null),)
    CROSS_COMPILE = i386-linux-gnu-
    endif

But it wouldn't propagate to the binman process calling this Makefile,
so it's better just raise an error and expect 'binman test' to be run
with a correct CROSS_COMPILE.

fe05701b05 binman: Build FIT image subentries with the section etype
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>;
				};
			};
		};

When binman is run from 'make check' it is given a toolpath so that the
latest tools (e.g. mkimage) are used. When run manually with no toolpath,
it relies on the system mkimage. But this may be missing or old.

7c15013639 binman: tegra: Adjust symbol calculation depending on end-at-4gb
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

example Intel requires that a FIT (Firmware Image Table) pointer be placed

d7fa4e4b22 binman: Split control.WriteEntryToImage() into separate functions
This code has three distinct phases:

1. The image is loaded and the state module is set up
2. The entry is written to the image
3. The image is repacked and written back to the file

Split the code out with three separate functions, one for each phase.

f86a736349 binman: Clean up all output directories in tests
At present some tests leave behind output directories. This happens
because some tests call binman, which sets up an output directory, then
call it again, which sets up another output directory and leaves the
original one behind.

Fix this by using a separate temporary directory when binman is called
twice, or by manually removing the output directory.

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.

7210c89eac binman: Update Entry.WriteData() to handle special sections
At present this method assumes that the parent section does not need
to recalculate its position or adjust any metadata it may contain. But
when the entry changes size this may not be true. Also if the parent
section is more than just a container (e.g. it is a CBFS) then the
section may need to regenerate its output.

Add a new WriteChildData() method to sections and call this from the
WriteData() method, to handle this situation.

a9cd39ef75 binman: Update Entry.ReadEntry() to work through classes
At present we simply extract the data directly from entries using the
image_pos information. This happens to work on current entry types, but
cannot work if the entry type encodes the data in some way. Update the
ReadData() method to provide the data by calling a new ReadChildData()
method in the parent. This allows the entry_Section class, or possibly
any other container class, to return the correct data in all cases.

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
loop.

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.

eba1f0cc94 binman: Add more tests for image header position
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.

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().
