elf: Add a way to read segment information from an ELF file

2022-02-22T17:05:44+00:00

Add a function which reads the segments and the entry address.

Also fix a comment nit in the tests while we are here.

binman: Support updating the dtb in an ELF file

2021-11-13T15:16:39+00:00

WIth EFI we must embed the devicetree in an ELF image so that it is loaded
as part of the executable file. We want it to include the binman
definition in there also, which in some cases cannot be created until the
ELF (u-boot) is built. Add an option to binman to support writing the
updated dtb to the ELF file u-boot.out

This is useful with the EFI app, which is always packaged as an ELF file.

binman: Support reading the offset of an ELF-file symbol

2021-11-13T15:16:39+00:00

Binman needs to be able to update the contents of an ELF file after it has
been build. To support this, add a function to locate the position of a
symbol's contents within the file.

Fix the comments on bss_data.c and Symbol while we are here.

binman: Support finding symbols in sub-sections

2021-01-30T21:25:41+00:00

At present binman only supports resolving symbols in the same section as
the binary that uses it. This is quite limited because we often need to
group entries into different sections.

Enhance the algorithm to search the entire image for symbols.

binman: Use target-specific tools when cross-compiling

2020-09-22T18:54:13+00:00

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.

patman: Move to absolute imports

2020-04-26T20:25:21+00:00

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).
