+Subject: [PATCH v2] u-boot: add libubootenv
+
+Add the new library libubootenv and remove fw_printenv and fw_setenv
+form u-boot-tools as the are now part of the new library.
+
+libubootenv is a library that provides a hardware independent
+way to access to U-Boot environment. U-Boot has its default environment
+compiled board-dependently and this means that tools to access the environment
+are also board specific, too.
+
+libubootenv conflicts with u-boot-tools from Debian 10
+as both try to install fw_printenv and fw_sentenv. This conflict is not
+part of the control file as it breaks the installation of custom u-boot-tools
+from the u-boot-sources.
