I have a fix now that I'm testing overnight and plan to post tomorrow, then we can decide whether it should be part of the same patch, or we should have two separate patches. Arnd

Thanks for fixing this one! I guess an ugly fix is better than nothing here.

MTD allows compile-time configuration of the possible CFI geometry settings that are allowed by the kernel, but that includes a couple of invalid configurations, where no bank width or no interleave setting is allowed. These are then caught with a compile-time warning: include/linux/mtd/cfi.h:76:2: warning: #warning No CONFIG_MTD_CFI_Ix selected. No NOR chip support can work. include/linux/mtd/map.h:145:2: warning: #warning "No CONFIG_MTD_MAP_BANK_WIDTH_xx selected. No NOR chip support can work" This is a bit annoying for randconfig tests, and can be avoided if we change the Kconfig logic to always select the simplest configuration when no other one is enabled.
