I can't say I've used that, but it appears to just be bit values. They
Partition Mask bit value
Add together the ones you need. For partitions 1 and 3, it would be
1+4, so... 5. I don't know if boot0cfg wants that as a plain decimal or
the leading 0x of a hex format, and the man page doesn't explicitly say.
It implies hex, but I suspect it wants decimal. Again, untested.
