Yes, I'm asking where it's appropriate to enable this new functionality
by default.  It certainly should be enabled on arm64 (there's new
designs) and riscv (there's new designs). It still ought to be enabled
on arm32 because we otherwise lack a easy way to say "new" arm32 (say
i.MX7) and not "old" arm32 (say i.MX23). What is the point of enabling
this on PowerPC for example? The active users there are (generally)
supporting legacy hardware and I have no idea how much they want to
change their boot process, once bootstd supports flash for example.
There's similar questions for everything else under arch/ as well.
