It might not be recommended (as I understand it, power management (or parts of it) is handled when the FPGA is set up), it might run hot (hotter than usual?).
Anyway, I tried it without the FPGA bitstream on the boot partition. U-boot complains:

fpga - loadable FPGA image support

Usage:
fpga [operation type] [device number] [image address] [image size]
fpga operations:
  dump	[dev]			Load device to memory buffer
  info	[dev]			list known device information
  load	[dev] [address] [size]	Load device from memory buffer
  loadb	[dev] [address] [size]	Load device from bitstream buffer (Xilinx only)
  loadmk [dev] [address]	Load device generated with mkimage
	For loadmk operating on FIT format uImage address must include
	subimage unit name in the form of addr:<subimg_uname>

Welcome to FreeBSD!

Full serial console output is on my Parallella FreeBSD page[1].
Do you want me to run more tests before I put the FPGA bitstream onto the boot partition?
