Any chance you can send me the wiring diagram?
I am using the same in my design but cannon make it work.
I found some documentation about this pin in the data sheet for the AR9331.
7.5 Power On Sequence
The AR9331 has an internal power on circuit
reset. when all power inputs, including
VDD33, VDD12 and VDD25, are ready, the
RESET_L signal; will be released from low to
high. This signal is connected to a digital
counter which controls the digital reset and is
released after 5 μs. When the digital reset goes
from low to high, the CPU begins fetching
instructions from the internal ROM or the
external SPI in order to boot the system.

If I understand this correct this is an output that can be used to hold external chips in reset until power is good and CPU starts.
