Looks like partition should not be defined in partitiontable anymore (?)

Looks like partition should not be defined in partitiontable anymore (?)

That's right, in ESP-IDF we haven't considered the partition table to be a partition so it doesn't need to be mentioned in the partition table.

The V3.0 partition tool didn't check that the first partition didn't clobber the partition table, so it will happily generate a binary partition table that includes an entry for the table itself. The V3.1 generator tool thinks that this partition will clobber the partition table, hence the warning (this is more important in V3.1 as you can change the offset of the partition table now, to allow a bigger bootloader).

At the moment the behaviour is to print a warning and modify the offsets so that they don't overlap, this is what caused the partition table to not fit in the flash. I'm going to change this so it's a hard error, to avoid people getting unexpected offsets in the binary tables.
