[PATCH 0/2] efi: add support for seeding the kernel RNG from UEFI

[Ard Biesheuvel]

This implements generic EFI core kernel code to seed the kernel entropy
pool from a Linux specific UEFI configuration table containing a random seed
supplied by the firmware. (#1)

In addition, it wires it up for ARM and arm64, by invoking the EFI_RNG_PROTOCOL
UEFI protocol from the stub, and populating such a UEFI config table using its
output.

How to wire this up for x86 is left as an exercise for the Intel developer.
