+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.
