If you are looking for a solution with D1, maybe you can talk to the people at Sipeed. They are the official sales outlet of Allwinner's D1 EVK outside the country (through Seeed Studio, they themselves handle tech support and a good part of the development of that board).

Sipeed started as a dev kit manufacturer, but now is focusing on solutions. I think you can have a wonderful collaboration with them.

FYI, D1 is designed to run Linux. I don't know if anyone has a working non-Linux BSP at all. If you do not want to reinvent all wheels, I'd suggest either you talk to someone who has intimate knowledge of the chip and its BSP, so that he or she can easily port the drivers to whatever OS you choose, or just use an MCU, not an MPU at all.

Don't know why it has to be SDIO, but if you just want to bridge Ethernet to an FPGA, consider using SPI. There are a lot of MCUs that have both an Ethernet MAC, sometimes even a PHY, and a fast SPI port. Take no more look other than ESP32, the most widely used IoT chip in the hobby, and you will find that it has all, even SDIO (though I'd avoid it due to patent issues).

Oh, BTW, the founder and owner of Sipeed also founded AI-Thinker, the company that propelled Espressif to what it is from just another discreet Chinese IoT chip manufacturer. If you want an ESP32 consultant, consider no more than her or her husband, a genius on chip designing, the designer of K210, and he "casually" designs 14nm chips at home.

Disclaimer: I know the people behind Sipeed well, though I do not work there nor do I get paid for promoting their services.

after years of fighting flash/ram sizes in MCU (PIC32, PSOC5, XMC4500, etc) the ability to program/buffer in a 64MB memory is unbelievable. we've had 10Base-T, then 100Base-T but very few MCU have 1000Base-T. one thing we fight in professional lighting displays is latency so the faster/wider the pipelines the better. we use an FPGA to take a buffer of lighting data and custom generate peripherals that are tailored to the pixel protocols. no need for fooling spi/uart to do the job with our custom drivers nailed to the protocol. not the only way to get there, just a path we are taking. we are near production on SSD212 products but they have been so difficult to work with on documentation. porting the drivers from linux to freertos when you don't know the register bits has been a pain in the ....

just our humble opinion after many years of product development.
