Hi Eugen, + Chanho,

In case CC_OPTIMIZE_FOR_DEBUG is set, unused code will not be optimized out, hence the reference to fpga_load will be compiled. if DM_FPGA and SPL_FPGA are not set, the build will fail with :
this is not correct. It is not DM_FPGA but only FPGA.
aarch64-none-linux-gnu-ld.bfd: common/spl/spl_fit.o: in function `spl_fit_upload_fpga': u-boot/common/spl/spl_fit.c:595: undefined reference to `fpga_load'
To solve this, added an inline empty stub in the header if CC_OPTIMIZE_FOR_DEBUG is set such that the build will succeed.

And when you enable CONFIG_CC_OPTIMIZE_FOR_DEBUG and FPGA you get compilation warnings.

I means please tune that condition properly not to create additional compilation warnings for other combinations.
Thanks, Michal
