Are there any FSBLs that pass "sifive,fu540-c000-prci0" ?  I am not aware 
of any. 

SiFive FSBLs have only ever used "sifive,aloeprci0" (or 
"sifive,ux00prci0") and those will soon be deprecated.

It would be good if the U-Boot maintainers would reject any DT compatible 
strings that haven't been committed upstream into the Linux kernel DT 
binding repository.  Otherwise I foresee this kind of mess increasing if 
others decide to invent their own compatible strings.
