Looks OK to me.  Once this goes in (with support for I2C and SPI EEPROMs)
then various RTC's NVRAM support can be updated too ... at a quick count,
that makes nine more drivers that can easily support this.

I kind of like letting Linux have the option of using this kind of
persistent storage, instead of keeping it so that only bootloaders
(and maybe some userspace code) ever touch it.
