>Description:
The evbarm port can also use /boot.cfg (at least some of the functionality, it
is used by bootaa64.efi) per comment from martin@ in the mailing list:

https://mail-index.netbsd.org/port-arm/2025/07/17/msg009321.html

BUGS section of boot.cfg(5) man page says:

     Support for boot.cfg is currently for NetBSD/i386 and NetBSD/amd64 only.
     It is hoped that its use will be extended to other appropriate ports that
     use the boot(8) interface.

Simple suggestion would be to update just the first sentence:

    Support for boot.cfg is currently for NetBSD/i386, NetBSD/amd64, and
    NetBSD/evbarm only.

However there is also distrib/sparc64/bootfs/boot.cfg so maybe that one as well?

>How-To-Repeat:
man boot.cfg
