Hello,
Following the support of the EyeQ5 SoC, this series adds the initial
support for a newer SoC, the EyeQ6H.
The EyeQ6H (or "High") from Mobileye is still based on the MIPS I6500
architecture as the EyeQ5. The 2 clusters of this SoC contain 4 cores
each, which are capable of running 4 threads per core. 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, among other features.
For now, this series just adds initial support with UART and Pinctrl
support. Another current limitation pointed out in patch 3 is that
only one CPU is actually running. This limitation will be solved with
upcoming series.
Regards,
Gregory

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.
