Doesn't matter, the wear leveling is independent of the partitioning
since it occurs at a lower level than a partition.

If it's an access point, why bother?  OpenWRT doesn't log permanently,
it just logs to tmpfs and that's it.  If you want a longer term storage
skip the SD card and remote log to another machine.  Most syslog daemons
will send the logs to a remote daemon.

The I/O performance of ext4 is somewhat better than ext2 but disabling
journaling is a good idea for a flash device.
