Yes, it's in the protected area. If you're thinking about applying upgrades though, you can do this from userspace using the /dev/flash-xxxx (?) files. You can flash everything that is flashable from there.

The initial code is very simple and doesn't rely on *anything* apart from working RAM to get into the reflasher - this means you should never not be able to reflash a unit. If you enter the test program, this doesn't even use a byte of RAM until the ram has been tested...
