Power supply
-
Put a load switch on +3.3V and +12V on both FMC slots allowing the FPGA to switch on/off the payload FMC voltages. Each voltage has to be controlled separately (2 enable lines).
-
Allow adjusting IC9 regulator output voltages and on/off state, the voltage has to be controlled from the AFPGA. The user should be able to choose the Vadj from the set of predefined values: +1.8V, +2.5V, +3.3V. By default Vadj should be OFF. Both slots share the same Vadj.

Adapt supply voltages for the Kintex-7 FPGA (1.0 Vcore/1.2V VGtx)
