Just the Versatile bit, and no I don't see any point in fixing the
other SoCs - it's an incentive for them to fix up their code.

However, given that hardly any have responded, pointing out this
problem in email clearly hasn't worked by the resounding silence
from SoC maintainers.

Removing boot_lock from those platforms who just cargo-culted the
boot_lock including comments without the pen_release stuff is easy,
all the lock is doing there is providing a bit of unnecessary
synchronisation between the requesting CPU and the booting CPU.
Only a couple of SoCs fall into this case - OMAP4 and qcom.

The rest aren't something that could just be ripped out without
the involvement of the SoC maintainer to test the changes - so
I'm of the opinion that we should just send SoC maintainers
patches that remove the pen_release and boot_lock crap.  If they
blindly accept the patches, so be it.

I'm preparing a series to attack some of this.
