Thu Jul 1 01:50:02 CEST 2021
The Gateworks GW7901 is an ARM based single board computer (SBC)
featuring:
- i.MX8M Mini SoC
- LPDDR4 DRAM
- eMMC FLASH
- SPI FRAM
- Gateworks System Controller (GSC)
- Atmel ATECC Crypto Authentication
- USB 2.0
- Microchip GbE Switch
- Multiple multi-protocol RS232/RS485/RS422 Serial ports
- onboard 802.11ac WiFi / BT
- microSD socket
- miniPCIe socket with PCIe, USB 2.0 and dual SIM sockets
- Wide range DC power input
- 802.3at PoE
To add support for this board:
- add dts from Linux (accepted for v5.14)
- add SPL PMIC config
