[U-Boot] QSPI "sf probe ...", "sf read ..." on Altera SoC FPGA

[RB23]

i checked, and if you mean these patches:
https://patchwork.ozlabs.org/patch/765992/
https://patchwork.ozlabs.org/patch/765996/
https://patchwork.ozlabs.org/patch/765997/
https://patchwork.ozlabs.org/patch/765998/

i already applied them, and they didn't work as well.

i also found these patches which i didn't try yet:
https://lists.denx.de/pipermail/u-boot/2017-May/292230.html

should i try those instead?
