devices should indicate if they use the write-protect pin and we should
either have this "enable on boot" as a global setting not specific to a
child device or ensure that multiple devices using the wp have the same
configuration of the wp on boot. In other words, if one device says
enable on boot and the other does not, then warn.

Which one of Jon's above suggestions would you prefer,

i.e.
writeprotect as a global setting for all devices
Or
Ensure that multiple devices using wp have same configuration

Or anything else you have in mind ?

If it's shared it can cause undesired effects on the mounted rootfs
if one device changes it. So some kind of checking for a shared case
should be available before a device is allowed to change it.

Ok, I will add a check for shared case.
