Reason: Improve power management.

Impact: None.

#9 Changed reset, enable and power-up structure with resistor R95, added transistor T2, and added resistor R128.

Type: Schematic Change

Reason: Improve module reset, enable, and power-up. !!! Add more information!!!

Impact: Changed Module reset, enable, and power-up handling . Please, verify that the is modified. That means that "EN1" signal from B2B connector enables DCDC U5 and can be monitored by CPLD U21 pin 27 (backward compatible mode with assembled resistor R95 and signal "EN1" as enable input), or that signal "EN1" only enables DCDC U5 and CPLD U21 pin 27 is connected to signal "POR_B" via voltage translator T2 (normal mode). Normal mode is the standard. Therefore, please, verify carefully which module meets your requierements and order the correct one.

#10 Added voltage level translator U29 and resistor R129 as assembly option to connect signal "PHY_LED1" to SoC.
