Colin Percival 5c73b3e0a3 Add support for getting early entropy from UEFI ... UEFI provides a protocol for accessing randomness. This is a good way to gather early entropy, especially when there's no driver for the RNG on the platform (as is the case on the Marvell Armada8k (MACCHIATObin) for now). If the entropy_efi_seed option is enabled in loader.conf (default: YES) obtain 2048 bytes of entropy from UEFI and pass is to the kernel as a "module" of name "efi_rng_seed" and type "boot_entropy_platform"; if present, ingest it into the kernel RNG.
