Add support for getting early entropy from UEFI

2022-03-14T21:26:33+00:00

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.

lualoader: fix the autoboot_delay countdown message

2022-03-09T21:21:54+00:00

When the timer drops from double to single digits, a spare 'e' is left
on the end of the line as we don't overwrite it. Include an extra space
at the end to account for this and overwrite the leftover character.

lualoader: use more concise verbiage for autoboot

2021-09-12T05:34:28+00:00

The behavior remains the same, but lualoader now uses the more concise
verbiage that forthloader used.  This is particularly important because
the previous line would exceed the right boundary of the menu and run
straight into space that would typically be allowed for the logo.

This makes it slightly easier to port logos from forthloader to
lualoader.

As we output spaces around the menu title, we should also check,
if the title is actually empty string.
