Add QSPI device tree to Stratix 10. Sync from Linux Stratix 10 dts.
Which tree? Which commit?
It is based on kernel v5.0 in mainline.
Tested on Stratix 10 SoC devkit. SOCFPGA_STRATIX10 # sf probe 0:0 SF: Detected mt25qu02g with page size 256 Bytes, erase size 64 KiB, total 256 MiB

v3->v4:
- Add qspi node to dtsi based on alphabetical order
- Add spi-tx-bus-width and spi-rx-bus-width
v2->v3:
- Change flash compatible to "jedec,spi-nor"
- Change spi-max-frequency to 100MHz

Does the Linux on havethis U-Boot specific property here? I could check myself if you would have given a tree or commit id of the sync source in the commit message...
If the Linux dts does not have this property, it would have to be moved to a U-Boot specific "-u-boot.dtsi" addon file.
Okay, will add this in new revision.
Thanks.
