  10 # Functionality and Pincount:
  11 * 5x RGMII Ethernet - 5x12 = **60 pins**
  12 * 2x USB ULPI - 2x12 = **24 pins**
  13 * GPIO (plain and EINT) - **? pins**
  14 * SDRAM - 16-bit data, 9-bit addr, rd/wr - **approx 30 pins?**
  15 * I2C - **2 pins**
  16 * SPI - assuming 4-pin - **4 pins**
  17 * QSPI - **6 pins**
  18 * JTAG - Can't read nmigen well enough, assuming TCK, TDO, TMS, TDI - **4 pins**
  19 * Power Vdd and Vss - **? pins**
  20
  21 Total (**not including power and GPIO pins**): 130 pins
