SubjectRe: [PATCH 3/3] MIPS: mobileye: Add EyeQ6H support
From


在 2024/5/6 17:16, Gregory CLEMENT 写道:
> 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.
