Resetting the board.

查到资料If DTS_FLAGS parameter omitted than following error will occur, because there is not enough space in the file, where the u-Boot can store some additional data about buses timing, etc.:
WARNING: could not create /chosen FDT_ERR_NOSPACE.
ERROR: /chosen node create failed - must RESET the board to recover.

解决方法 make ARCH=powerpc mpc8315erdb.dtb DTS_FLAGS="-S65536"
