-Subject: [PATCH] tools/env/fw_env.h: remove env.h
-
-As reported by Nicolas Carrier on the Buildroot mailing list [1],
-there is a new build issue while building a program which interacts with
-the u-boot environment. This program uses the headers of the ubootenv
-library provided by uboot-tools.
-
-This is an upstream change from uboot [2] adding "#include <env.h>" to
-fw_env.h. Adding env.h require a board configuration to build.
-
-But only fw_env.h header is installed in the staging directory by
-uboot-tools package, but since it now include env.h the build is broken
-because env.h is missing from the staging directory.
-
-It's seems an upstream bug since env_set() is not used in fw_env tool.
-
-Adding env.h is an error since it also include compiler.h (and others
-uboot internal includes).
-
-Nicolas removed env.h from fw_env tool and fixed it's build issue.
-
-This problem is present since uboot v2019.10, so the uboot version
-present in Buildroot 2020.02 is affected.
