Is it possible to save/restore the UEFI configuration

[offsides]

It appears that all the configuration in the UEFI setup is saved in the RPI_EFI.fd file, which is replaced any time the UEFI firmware is upgraded. Is it possible to save that data to a separate file, and either manually or (even better) automatically restore it when the firmware is upgraded? Otherwise I have to go into the UEFI setup and turn off the 3GB limit every time I upgrade the UEFI firmware.

Thanks!

In my mind the solution to this will be the same as the solution to #102. That said, there has been some talk of actually taking over a bit of the SPI flash for them as well, but AFAIK, we need to get the pi foundation on board with that.

Yes, read the dmpstore UEFI Shell command manual. It can dump variables to a text file and import them from there.

This will no longer be an issue if we save the UEFI variables in SPI EEPROM (#6 )

@samerhaj, also having a way to set them in a file would be quite liberating, because we could pre-prepare the sdcard in advance with the required variables (as-in #210).
