That has an effect, if this option is turnned off:

cdl_option CYGSEM_REDBOOT_FLASH_COMBINED_FIS_AND_CONFIG {user_falue 0};
                                                         ^^^^^^^^^^^^
So, try such an import before make

...
cat <<_EOF | ecosconfig import /dev/stdin
cdl_option CYGSEM_REDBOOT_FLASH_COMBINED_FIS_AND_CONFIG {user_value 0};
cdl_option CYGNUM_REDBOOT_FLASH_CONFIG_BLOCK {user_value -4};
_EOF

Then fulfil `fconf -i', `fis init -f' as you do it as well and compare
the `fis list' results. I get the expected changes on my target.
