Subject: [PATCH 11/13] MIPS: Add Mobileye EyeQ6Lplus evaluation board dts
Add the device tree of the evaluation board of the EyeQ6Lplus SoC.
The board comes with 2GB of RAM, an SPI NAND connected to the octoSPI
controller, and the two SPI controllers are connected to each other via
an intermediate MCU for loopback testing. The UART of the SoC is used
as the serial console.
