Hi,
just tested this on my cyclone5 board, but unfortunately without success.

---
U-Boot SPL 2017.09-00354-g824def8 (Sep 27 2017 - 06:47:19)
(....)
Hit any key to stop autoboot:  0
=> sf probe
SF: Detected n25q512 with page size 256 Bytes, erase size 64 KiB, total 
64 MiB
### ERROR ### Please RESET the board ###
----

same behavior as before.

But the good news are, that a colleague of mine successfully brought up 
a custom board with this patch.
Prior he had trouble in SPL accessing the flash.

I will poke him to give some "tested-by" credits on this.

cheers,
Hannes
