socfpga: ethernet problem

[Antony Pavlov]

Hi!

Barebox for DE0-Nano-SoC succesfully starts on Terasic DE10-Nano board
but there is an ethernet issue.

After `make ARCH=arm socfpga_defconfig` I see that the CONFIG_DRIVER_NET_DESIGNWARE_SOCFPGA
option is disabled.

  #
  # Network drivers
  #
  ...
  CONFIG_DRIVER_NET_DESIGNWARE=y
  # CONFIG_DRIVER_NET_DESIGNWARE_GENERIC is not set
  # CONFIG_DRIVER_NET_DESIGNWARE_SOCFPGA is not set

after enabling CONFIG_DRIVER_NET_DESIGNWARE_SOCFPGA I see 'Could not get sysmgr-syscon node'
error message:
