FreeBSD doesn't require the PL to be programmed.  The PL can be 
programmed any time using the devcfg(4) driver.  But if you need 
something in the PL at initialization time, a bitstream can be included 
in BOOT.BIN which is generated using Xilinx tools.

Another option would be to create an rc script that programs the PL at 
boot-up using the method described in devcfg(4) man page.
