i.Core STM32MP1 is an EDIMM SoM based on STM32MP157A from Engicam. General features: - STM32MP157A - Up to 1GB DDR3L - 4GB eMMC - 10/100 Ethernet - USB 2.0 Host/OTG - I2S - MIPI DSI to LVDS - rest of STM32MP157A features i.Core STM32MP1 needs to mount on top of Engicam baseboards for creating complete platform solutions. Add support for it.
