Russell, Tony: should mailbox_mach, a module that checks for logical
devices be always built-in?

I think that's the easiest... in my patches I moved the
architecture-specific code from mach-omapX/devices.c to
mach-omapX/mailbox.c, so both the logical devices and real platform
devices are in the same code, and can be built-in.

This way, there's no need to rely on services like udev to load
mailbox, then mailbox_mach, then bridgedriver. After all, all
mailbox_mach is doing is calling functions in mailbox to register the
logical devices.

Judging from:
http://article.gmane.org/gmane.linux.ports.arm.kernel/58555

The answer is yes.
