See doc/README.socfpga . The out of tree tools generate board/bitstream 
specific input header files which you plug into the qts-filter.sh script 
, those files contain the CONFIG_* macros and those files get converted 
by the qts-filter.sh script into the output header files in 
board/*/qts/*.h . The output header files are what is used by U-Boot then.
