2019-10-15binman: Allow symbols to be resolved inside sectionsSimon Glass
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(). Signed-off-by: Simon Glass <sjg@chromium.org>
2019-10-15binman: Clean up unnecessary code related to ELF test filesSimon Glass
We use the Makefile for all ELF test files now, so drop all the code that checks whether to get the test file from the Makefile or from the git repo. Also add a comment to the Makefile indicating that it is run from binman. Signed-off-by: Simon Glass <sjg@chromium.org>

2019-10-15binman: Use the Makefile for u_boot_binman_symsSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>

2019-10-15binman: Use the Makefile for u_boot_ucode_ptrSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-10-15binman: Use the Makefile to build ELF test filesSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-10-15binman: Use tools.Run() to run objdumpSimon Glass
At present this command silently fails if something goes wrong. Use the tools.Run() function instead, since it reports errors. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-10-15binman: Fix IFWI output when using an Intel FIT imageSimon Glass
At present this entry does not work correctly when a FIT image is used as the input. It updates the FIT instead of the output image. The test passed because the FIT image happened to have the right data already. Fix it. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-10-15binman: Add support for Intel FITSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-10-15binman: x86: Separate out 16-bit reset and init codeSimon Glass
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. Make use of the new 'reset' entry and change the existing 16-bit entry to include just the 16-bit data. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-10-15binman: Add support for an x86 'reset' sectionSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-10-15binman: Correct use of 'replace' in IFWI testsSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-10-15binman: Handle hidden symbols in ELF filesSimon Glass
Some versions of binutils generate hidden symbols which are currently not parsed by binman. Correct this. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-10-15binman: Drop .note section from ELFSimon Glass
Recent versions of binutils add a '.note.gnu.property' into the ELF file. This is not required and interferes with the expected output. Drop it. Also fix testMakeElf() to use a different file for input and output. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-10-15binman: Allow use of help and entry-docs without libfdtSimon Glass
At present if libfdt is not available binman can't do anything much. Improve the situation a little. Ideally there should be a test to cover this, but I'm not quite sure how to fake this. Signed-off-by: Simon Glass <sjg@chromium.org> (fixed up missing ReadChildData() enty test)
2019-10-15binman: Use cls instead of self for class methodsSimon Glass
It is more common to use the name 'cls' for the class object of a class method, to distinguish it from normal methods, which use 'self' Update the binman tests accordingly. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-10-11binman: Use qemu-x86_defconfig in the exampleBin Meng
The doc currently uses sandbox_defconfig as examples of enabling debug/verbose output of binman. However during a sandbox build it does not call binman at all. Change it to qemu-x86_defconfig. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2019-10-08binman: Take account of skip-at-start with image-headerSimon Glass
The image-header currently sets it offset assuming that skip-at-start is zero. This does not work on x86 where offsets end at 4GB. Add in this value so that the offset is correct. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Bin Meng <bmeng.cn@gmail.com>
2019-10-08binman: Handle reading data for end-at-4gb sectionsSimon Glass
Some x86 sections have special offsets which currently result in empty data being returned from the 'extract' command. Fix this by taking account of the skip-at-start property. Add a little more debugging while we are here. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Bin Meng <bmeng.cn@gmail.com>
2019-10-08binman: Add a base implementation of Entry.ReadChildData()Simon Glass

2019-10-08binman: Allow verbose output with all commandsSimon Glass
At present the verbose flag only works for the 'build' command. This is not intended, nor is it useful. Update the code to support the verbose flag and make use of a command exception handler.

2019-07-29binman: Split control.WriteEntryToImage() into separate functionsSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-29binman: Update control.WriteEntry() to support writing the mapSimon Glass

2019-07-29binman: Move control.WriteEntry further down the fileSimon Glass
Move this function after the extraction logic so we can keep the writing logic in one place. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-29binman: Clean up all output directories in testsSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-29binman: Add a test function to clean up the output dirSimon Glass
Put tearDown()'s logic into a new _CleanupOutputDir() function so that it can be called from elsewhere. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-29binman: Update state when replacing device-tree entriesSimon Glass
Since the state module holds references to all the device trees used by binman, it must be updated when the device trees are updated. Add support for this. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-29binman: Support replacing data in a cbfsSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-29binman: Update Entry.WriteData() to handle special sectionsSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-29binman: Update Entry.ReadEntry() to work through classesSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>

2019-07-29binman: Place Intel descriptor at image startSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-29binman: Adjust fmap to ignore CBFS filesSimon Glass
The FMAP is not intended to show the files inside a CBFS. The FMAP can be used to locate the CBFS itself, but then the CBFS must be read to find out what is in it. Update the FMAP to work this way and add some debugging while we are here. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-29binman: Support shrinking a entry after packingSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-29binman: Update the _testing entry to support shrinkageSimon Glass
Sometimes entries shrink after packing. As a start towards supporting this, update the _testing entry to handle the test case. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-29binman: Allow updating entries that change sizeSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-29binman: Add more tests for image header positionSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-29binman: Move Image.BuildImage() into a single functionSimon Glass

2019-07-29binman: Write the original input fdtmap to a fileSimon Glass

2019-07-29binman: Add info to allow safely repacking an image laterSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-29binman: Support updating entries in an existing imageSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-29binman: Tidy up _SetupDtb() to use its own temporary fileSimon Glass
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(). Signed-off-by: Simon Glass <sjg@chromium.org>
2019-07-29binman: Allow the fdtmap to remain unchangedSimon Glass
