Kernel driver found here:
https://elixir.bootlin.com/linux/v5.4-rc6/source/drivers/rtc/rtc-ds3232.c
did register NVMEM of 236 bytes with the kernel.

M41T80 chip also supports this feature. However, qemu does not support

Hi,
Thanks Stefan ! I spoke to Dinah and this issue is still up for grabs.
I would be working on both SeaBIOS MMConfig task and the DS3231 RTC

Thanks for your help!
