| # - that echos out the u-boot version |
| # - include the main u-boot makefile |
| # This lets the u-boot makefile logic do all its crazy stuff without |
| # worrying about it (which we would if we tried to sed/grep it out). |
| # |
| # The make command will read the temporary makefile from stdin and |
