running sf probe on one of my clearfogs with this set of patches applied I got

Do you use the clearfog_defconfig?
yes I did, I am testing on a clearfog pro
Does current U-Boot master work for you?
2018.03 fails the same. I have another clearfog pro and a clearfog base I can test with, though I have the internal mmc on my base and now wish I had not done so.
For the record, on my Clearfog Base 'sf probe' shows:
SF: Detected w25q32bv with page size 256 Bytes, erase size 4 KiB, total 4 MiB
This works with or without these patches.
mine does not work either way, so it is no worse off. I would like to put u-boot in SPI on them all
Can you read/write the SPI flash from Linux?
Sorry, I have been travelling, I can not access the SPI flash from Linux, I currently do not have physical access to my solid-run based boards. Nothing in my testing is any worse off.

Add the "spi-flash" compatible string so that the generic sf_probe driver can probe the SPI flash on the SolidRun SOM.
