I will check with the author!

BTW: My patch works fine on top of v2019.04 but the boot hangs without
console output with the latest HEAD. The problems start with commit:

  ede6e7b reset: socfpga: add reset handling for old kernels

Then I get:

  U-Boot SPL 2019.04-00508-g03b5c7e-dirty (May 07 2019 - 21:03:52 +0200)
  ### ERROR ### Please RESET the board ###

Any idea how to fix that?
