OPAL unconditionally enters secondary CPUs with only HV and SF set. I tried writing a secondary entry point instead, but OPAL rejected it and I am unsure why, so I resorted to making the system reset interrupt endian-flexible. This means we take a slight performance hit on wakeup on LE, but it is a good stopgap until we can figure out a reliable way to make OPAL enter where we want it to. It probably makes sense to have it around anyway, because I can imagine scenarios where the cpu resets itself to BE and does a software reset. Sponsored by: Tag1 Consulting, Inc.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
