The Parallella board comes with a U-Boot bootloader that loads one of two predefined FPGA bitstreams before booting the kernel. Both define an AXI interface to the on-board Epiphany processor. Enable clocks FCLK0..FCLK3 for the Programmable Logic by default. Otherwise accessing, e.g., the ESYSRESET register freezes the board, as seen with the Epiphany SDK tools e-reset and e-hw-rev, using /dev/mem.
