I think we can add one new config for FPGA is programmed or not.
However, i think this should be as default since most intel fpga
devkits have this feature, but user can edit the environment in code,
or in boot console. I prefer not to hard code this in the code like
what previously doing in gen5. DO you have any better idea?
