JTAG Pinouts
JTAG pins were found by removing the BGA from a WNR2000 and a TP-Link WR-1043ND (AR9132 with JTAG header) and comparing the PCB traces. The top side of the PCB is the one with the heatsinks.

^ Name ^ BGA pin ^ Top/Bottom of PCB ^ Location on PCB ^ | TMS  | G20 | bottom | R335 towards C324 | | TDO  | G21 | top    | TP34 | | nTRST | F22 | top   | R68 toward CPU  | | TCK  | F21 | top    | R336 toward CPU | | TDI  | G22 | top    | R334 toward CPU | | nSRST | D22 | top   | U8 toward R262  |

(Be aware that there is no "I" row in the BGA counting!)
