binman: Support accessing binman tables at run time

2017-12-13T02:53:45Z

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.

binman: Support enabling debug in tests

2017-12-13T02:53:45Z

The elf module can provide some debugging information to assist with figuring out what is going wrong. This is also useful in tests. Update the -D option so that it is passed through to tests as well. Signed-off-by: Simon Glass

binman: Add a function to read ELF symbols

2017-12-13T02:53:45Z

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. Signed-off-by: Simon Glass

binman: Return non-zero exit code on test failure

2017-11-23T01:05:38Z

Return exit code 1 when test fail so that callers can detect this. Signed-off-by: Simon Glass

binman: Check for files missing from test coverage

2017-11-23T01:05:38Z

Files that are never imported are not shown in the test-coverage report. Detect these and show an error. Signed-off-by: Simon Glass

binman: Add tests for importlib availability

2017-11-23T01:05:38Z

Add a test that the 'entry' module works with or without importlib. The tests are numbered so that they are executed in the correct order. Signed-off-by: Simon Glass

binman: Append to PYTHONPATH when running test coverage

2017-11-23T01:05:38Z

Rather that overwrite this, append to it, in case the caller has already set up the path correctly. Signed-off-by: Simon Glass

binman: Rename tests to ftest

2017-11-23T01:05:38Z

At present these tests use the same filename as patman. This adds confusion when running all tests, since error messages look very similar. In fact binman tries to run the wrong tests at present. Rename the tests. Signed-off-by: Simon Glass

pylibfdt: move pylibfdt to scripts/dtc/pylibfdt and refactor makefile

2017-11-17T12:43:32Z

The pylibfdt is used by dtoc (and, indirectly by binman), but there is no reason why it must be generated in the tools/ directory. Recently, U-Boot switched over to the bundled DTC, and the directory structure under scripts/dtc/ now mirrors the upstream DTC project. So, scripts/dtc/pylibfdt is the best location. I also rewrote the Makefile in a cleaner Kbuild style. The scripts from the upstream have been moved as follows: lib/libfdt/pylibfdt/setup.py -> scripts/dtc/pylibfdt/setup.py lib/libfdt/pylibfdt/libfdt.i -> scripts/dtc/pylibfdt/libfdt.i_shipped The .i_shipped is coped to .i during building because the .i must be located in the objtree when we build it out of tree.

binman: Put our local modules ahead of system modules

2017-07-11T16:08:20Z

If a system module is named the same as one of those used by binman we currently pick the system module. Adjust the ordering so that our modules are chosen instead. The module conflict reported was 'tools' from jira-python. I cannot access that package to test it. Signed-off-by: Simon Glass Reported-by: Kevin Hilman Acked-by: Kevin Hilman
