This is needed for the SoCFPGA booting from SPI NOR flash e.g. (N25Q256A). With these changes, the SoCrates can boot and re-boot (reset) from SPI NOR flash without any problems.
Seems like your SPI NOR reset logic is buggy. Does any of [1] apply to your board please?

Yes. This seems to be that case. But I can't change it right now. So this "solution" with the soft-reset is better than nothing.
If this is some think that must require, any possibility to this resetting prior to u-boot? like preloader or in first stage boot loader or something.
I feel this is mostly a kind of hardware treat, and looks like it's touching generic sf framework which is not so good.
thanks!
