I do not have a board with an EFI bootloader, so that may explain why I
didn't managed to reproduce your issue. I really would prefer to make
the driver less depend to the bootloader than the firmware de-initialize
the RNG before booting. However both things could be done independently.
I can have a look on the driver but as I don't have the configuration I
may ask you to test it for me.
