patman: Move to absolute imports

2020-04-26T20:25:21Z

At present patman sets the python path on startup so that it can access the libraries it needs. If we convert to use absolute imports this is not necessary. Move patman to use absolute imports. This requires changes in tools which use the patman libraries (which is most of them). Signed-off-by: Simon Glass

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

2019-11-11T19:20:35Z

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 Fixes: 15c981cc (binman: Correct symbol calculation with non-zero image base) Signed-off-by: Simon Glass Tested-by: Stephen Warren

binman: Allow support for writing a size symbol to binaries

2019-10-15T14:40:02Z

It is useful to be able to access the size of an image in SPL, with something like: binman_sym_declare(unsigned long, u_boot_any, size); ... ulong u_boot_size = binman_sym(ulong, u_boot_any, size); Add support for this and update the tests. Signed-off-by: Simon Glass

binman: Clean up unnecessary code related to ELF test files

2019-10-15T14:40:02Z

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

binman: Use the Makefile for u_boot_binman_syms_bad

Remove this file from git and instead build it using the Makefile. Signed-off-by: Simon Glass

binman: Use the Makefile for u_boot_binman_syms

2019-10-15T14:40:02Z

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

binman: Use the Makefile for u_boot_ucode_ptr

2019-10-15T14:40:02Z

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
