Thanks for working on this! Are you also planning on adding the features of the FSBL to U-Boot to remove it from the boot flow? I was able to run U-Boot and boot Linux successfully on a SiFive HiFive Unleashed board with this patch series. I had to make one more change, because U-Boot was not able to find a serial driver and paniced as a result. I fixed this by making the serial driver available pre-relocation. For this, the soc compatible has to be added to cpu/generic/cpu.c and the serial driver must have the DM_FLAG_PRE_RELOC flag set. Another way would be to add a "stdout-path" property to the chosen node of the device tree.
