This is how we try to do now, fw_setenv is built per machine but it is enough that u-boot-fw-utils is built in a different version as u-boot to get a mess. > OR fix fw_setenv to take env defaults from a file or somesuch ? Right, I interprete this patch as a step in this direction. This patch generates a default that can be used as input for fw_setenv.
