Attached are the two patch files. They were generated from
include/linux/bcm47xx_nvram.h and from 

Sorry about the confusion regarding the


I was looking at an older repo where this patch was different.

NVRAM driver is part of upstream kernel, it's just living in arch/mips/ for now:

bcm53xx's file is just a copy of above and that would be the best to
keep it this way.

I think you may prepare patch on top of
drivers/firmware/broadcom/bcm47xx_nvram.c for now, then we can work on
upstreaming it. Meanwhile I'll be happy to add your patch to

It doesn't matter if you work on top of
110-firmware-backport-NVRAM-driver.patch, it doesn't even touch
