Greetings. Please let me know if there is a better place to ask this question.
Any clues here? I've got an AllWinner H5 with Winbond SPI flash attached on SPI0. The flash is programmed using the sunxi FEL tools and boots perfectly. Now I'd like to save the environment there too.

Existing controller cann't handle SPI on H5, try below branch [1] it has sun6i spi driver and sample patch for sopine.
