How about making a subtarget for NAND devices? The kernel config will be 
separate so we can disable NVMEM for that subtarget.

You mentioned contacting Broadcom regarding this issue around 6 months 
ago. Any news on that?

I've got no interest to learn the NVMEM subsystem to take a crack at 
fixing it at the moment. For now, the best I can do is send a separate 
mail to openwrt-devel as a mean to report this bug.
