Hi Michael,
Since this is the first time I've submitted code to the Linux community, please forgive me for some of the missteps that I've made.
I uploaded the incorrect patch file.
In a previous e-mail you said：
XMC parts seem to have SFDP tables and they should work out of the box
without any patches with the generic spi nor driver [1]. Therefore,
you don't need any entry at all.

I think it is related to the PARSE_SFDP flag.
The XMC flash part supports SFDP, so i don’t need to add NO_SFDP_FLAGS() macro.
