22 # Functionality and Pincount (NOT FINAL, LIKELY TO CHANGE):
26 * 5x RGMII Ethernet - 5x18 = 90 pins [[shakti/m_class/RGMII/]]
27 * 2x USB ULPI - 2x12 = 24 pins [[shakti/m_class/ULPI/]]
28 * SDRAM - 39 pins [[shakti/m_class/sdram/]]
30 * JTAG - 4 pins [[shakti/m_class/JTAG/]]
31 * 1.8v Core Power Vdd - 13 pins
32 * 1.8v Core Power Vss - 13 pins
33 * 3.3v IO Power Vdd - 10 pins
34 * 3.3v IO Power Vss - 10 pins
37 * SPI - 4 pins [[shakti/m_class/SPI/]]
44 * QSPI - Could share with SPI - 6 pins [[shakti/m_class/QSPI/]]
45 * SD/MMC - Could share with SPI - 4 pins
47 Total: **246** pins (10 spare)
49 GPIO, EINT, Vdd, Vss, SDRAM, reset, PLL pin counts come from the LS180 pinmux definitions.
51 RGMII pinout count comes from [here](https://web.pa.msu.edu/hep/atlas/l1calo/hub/hardware/components/micrel/rgmii_specification_hp_v1.3_dec_2000.pdf)
