[PATCH v2 3/3] MIPS: mobileye: Add EyeQ6H support

Gregory CLEMENT
2024-05-13T18:34:46Z

EyeQ6H (or “High”) is an other SoC from Mobileye still based on the
MIPS I6500 architecture as the EyeQ5. The 2 clusters of this SoC
contains 4 cores which are capable of running 4 threads. Besides this,
it features multiple controllers such as the classic UART, high speed
I2C, SPI, as well as CAN-FD, PCIe Gen4, Octal/Quad SPI Flash
interface, Gigabit Ethernet, MIPI CSI-2, MIPI DSI, and eMMC 5.1. It
also includes a Hardware Security Module, Functional Safety Hardware,
and video encoders and more.

This commit provides the infrastructure to build a kernel running on
EyeQ6H SoC. For now the support is limited and only one CPU core is
running.
