Originally added in aa701b94336b358798d676eef12a7b90bdac23f5
Before this patch, there was a hard-coded env that was used as default if the env in flash is detected as invalid. Now this tool (compiled for a given board) will share the default env with the u-boot for the board.
Fix include of config.h
Need to define "TEXT_BASE" when building the fw_env tool so that the default env will be correct for environments which use it.
Define __ASSEMBLY__ when calling #include <config.h> so that we only get #defines (all we're interested in).
