Hi
I compile the master branch u-boot for LicheePi Zero,
it's not working.I'm trying to fix the the issue, it's working
but ugly now.
I didn't figure out why the sunxi_spi_probe function in
drivers/spi/sunxi_spi.c was not called automatically.
Finally, I add code to probe all spi device manually.
My patch is shown below, what's the correct way to fix it?
