     49 * Replace 4-port PCIe switch with 3-port. This removes PCIe routing to Mini-PCIe slot J10. Remove U3 multiplexer.
     50 * Switch direction of D9 diode for testing protection
     51 * Improve RJ45 LED brightness
     52 * Improve PCIe capacitor values
     53 * Add series capacitors to USBHUB_TXP2/TXN2 lines
     54 * Use threaded holes for SOM and MIPI
     55 * Upgrade RTC battery to rechargeable and remove GSC LDO
     56 * Add pull-up line on USDHC2_RSTJ
     57 * Improve power supply at 60V levels with capacitance
     58 * Add TVS diode on power input for high voltage scenarios
     59 * Add series resistor to POE PGOOD signal
     60 * Improve D16 PoE Controller Diode for layout reasons
     61 * Remove pull down resistor from WAD circuit
     62 * Improve D7 diode for simplicity
