[U-Boot] [PATCH] ARM: Add Support for the VInCo platform
Gregory CLEMENT
gregory.clement at free-electrons.com
Wed Dec 16 11:34:00 CET 2015
The Versatile Industrial Communication platform is a community oriented
board from Landis + Gyr. It comes with:
- an RS-485 port
- 2 Ethernet ports
- a wireless M-BUS
- a 4G modem
- a 4MB SPI flash
- a 4GB eMMC
