Configuring FPGA from HPS on SoCKit board

Hi everybody!

I'v managed to boot Linux from QSPI-flash on SoCKit board, but I can't configure FPGA from QSPI-flash. I'm trying to configure FPGA from preloader as shown in

GSRD v13.1- Programming FPGA from HPS.

I created 3 partitions for QSPI and wrote fpga.rbf file into /dev/mtd2, rebuilt preloader (after making changes in socfpga_common.h file) and flash it into /dev/mtd1. After powering the board I got

U-Boot SPL 2013.01.01 (Apr 10 2018 - 11:59:25)

into the Linux console... I've tried MSEL="00000" and "01010", but without any success. Bootsel = "111" (boot from QSPI).

If I change the preloader to another one (without FPGA from QSPI configuring support) Linux normally starts from QSPI...

Any help will be appreciated.
