With CONFIG_LTO enabled the current way of extracting the configured environment no longer works, i.e. the object file content changes due to LTO. Build a host tool which prints the configured environment instead of using objcopy and friends to achive the same. The code and Makefile changes were mostly stolen from tools/env/ i.e. the target userspace tools to access the environment. Changes in v4: - add '(objtree)/' when calling the tool. Suggested by Pali Rohár. - renamed patch, as more than just the Makefile has changes Changes in v3: - moved the tool from scripts/ to tools/. Suggested by Tom Rini - changed the dependencies to '$(env_h)' and 'tools'. Suggested by Tom Rini and Pali Rohár. - removed the sed rule which replaces \x00 with \x0A as this is already done by the tool. Suggested by Pali Rohár. Changes in v2: - reworked to build a host tool which prints the configured environment as proposed by Pali Rohár https://lore.kernel.org/u-boot/20221018174827.1393211-1-max.oss...@gmail.com/ - renamed patch, v1 used "Makefile: fix u-boot-initial-env target if lto is enabled" Max Krummenacher (1): u-boot-initial-env: rework make target Makefile | 9 +++++---- tools/.gitignore | 1 + tools/Makefile | 3 +++ tools/printinitialenv.c | 44 +++++++++++++++++++++++++++++++++++++++++ 4 files changed, 53 insertions(+), 4 deletions(-) create mode 100644 tools/printinitialenv.c -- 2.35.3
