pre-wrap;">add RMII clock output<br><br>The TLK106 Ethernet PHY requires a 50 MHz input on XI in RMII mode.<br>RMII_CLOCK is connected on the micro-controller on PA14 and PB11.<br>PA14, with note "GTXCR" on the schematic, cannot be use to provide<br>the 50 MHz clock since this is the clock output for GLK[0], which<br>is reserved for the CPU running at 120 MHz.<br>PB11 is the clock output pin for GCLK[5], which now divides DPLL1<br>at 100 MHz to the required 50 MHz.<br>WARNING: I did not test if the output clock signal matches the<br>requirement of the input clock signal.<br><br>Change-Id:
