+Subject: [PATCH] drop configh from tools
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+We need to build u-boot tools without a board configuration for the target.
+fw_env just uses config.h to define the default environment of the created
+image, so it really isn't mandatory.
