No, sorry, I ended up droping that patch.

You mention that the Pine64 LTS has an SPI flash, yet you change the
sopine baseboard dts. Why is that?

 There is still no dts for Pine64-LTS (Andre latest serie address that).
 Note that the sopine.dtsi already have the SPI node, the patch is
present in sunxi/dt64-for-4.19
