I don't think that is bug, this is how the build order is designed,
Kconfig is build 1st, then only compiling the header/C files. So i
would suggest all related/dependency CONFIG put in one place,either all
in Kconfig or in header file. 

So, i suggest to submit a seprate patch for converting all to Kconfig
after this patchset, or i can pull this patch into this patchset.

If you prefer adding SPL_FPGA_SUPPORT into this patchset, i need to
rerun the tool for this macro, because a lot defconfigs require FPGA
feature enabled in SPL build. I also need to run all defconfigs
compilation and make sure above example is not hit, otherwise FPGA
driver could be failed in the build.

What do you think?

Thanks.
