There is no reason not to use the Linux "jedec,spi-nor" binding in u-boot. This patch adds this compatible into sf_probe and will avoid changing the device tree files to add a u-boot specific compatible to probe a spi flash.
This change is needed to enable SPI NOR Flash support using the non-modified device tree file for Amlogic Meson GX SoC based boards.

This is definitively a move in the right direction! I was only days away from sending this myself ;-)

I would still need more changes to U-Boot to boot the Linux socfpga devicetrees without patches (they have compatible = "n25q256a" etc.), but then again, maybe it's easier to change the Linux ones to include "jedec,spi-nor" than trying the effort of changing U-Boot here...
It's better to revert/remove "spi-flash" from Linux sync dts(s) files along with this compatible change, u-boot specific stuff like sandbox still use the legacy.
