ARM: dts: stm32: add STM32MP1-based Linux Automation MC-1 board
The Linux Automation MC-1 is a SBC built around the Octavo Systems OSD32MP15x SiP. The SiP features up to 1 GB DDR3 RAM, EEPROM and a PMIC. The board has eMMC and a SD slot for storage and GbE for both connectivity and power. Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Signed-off-by: Alexandre Torgue <alexandre.torgue@st.com>
