 * SERDES for Ethernet - using LiteX and [Marvell PHY](https://www.mouser.com/ProductDetail/Marvell/88E1512-A0-NNP2I000?qs=vdi0iO8H4N0XzuXqBRxTqg%3D%3D)
 * Noting that a SERDES to RGMII PHY is $20(kinda expensive for total cost of an SBC), we can instead do Eth over USB like the original RPI. This moves the complexity to software - could make doing eth things during boot loader a little more complex.
