m68k: Rework BI_VIRT_RNG_SEED as BI_RNG_SEED

2022-11-16T09:03:48Z

commit dc63a086daee92c63e392e4e7cd7ed61f3693026 upstream. This is useful on !virt platforms for kexec, so change things from BI_VIRT_RNG_SEED to be BI_RNG_SEED, and simply remove BI_VIRT_RNG_SEED because it only ever lasted one release, and nothing is broken by not having it. At the same time, keep a comment noting that it's been removed, so that ID isn't reused. In addition, we previously documented 2-byte alignment, but 4-byte alignment is actually necessary, so update that comment.

m68k: virt: Use RNG seed from bootinfo block

2022-07-06T12:07:04Z

Other virt VMs can pass RNG seeds via the "rng-seed" device tree property or via UEFI, but m68k doesn't have either. Instead it has its own bootinfo protocol. So this commit adds support for receiving a RNG seed from it, which will be used at the earliest possible time in boot, just like device tree. Reviewed-by: Laurent Vivier Signed-off-by: Jason A.
