socfpga: ethernet problem

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:

Patch opportunity:

DRIVER_NET_DESIGNWARE_SOCFPGA is missing a
    select MFD_SYSCON

and the defconfig should be regenerated with the socfpga driver instead.

I made changes you suggest. Now ethernet works!

Many thanks!

Now I still have some minor issues with DE10-Nano:

  * socfpga-xload-2_defconfig does not work but socfpga-xload_defconfig does;
  * 'sleep 1' longs for 5 seconds.

I suppose that DE10-Nano is somewhat differ with DE0-Nano-SoC.
