Hello, NXP's S32V234[1] ("Treerunner") vision microprocessors are targeted for high-performance, computationally intensive vision and sensor fusion applications that require automotive safety levels. They include leading edge Camera Vision modules like APEX-2, ISP and GPU. The S32V234-EVB and S32V234-SBC boards are available for customer evaluation. The following patch series introduces minimal enablement support for the NXP S32V234-EVB2[2] board, which leverages most of the SoC capabilities. The series includes a driver for operating the on-chip LINFlexD controller in UART mode. In the future, we aim to submit multiple drivers upstream, which can be found in the kernel of our Auto Linux BSP[3] ("ALB"), starting with basic pinmuxing, clock and uSDHC drivers. For validation, you can use the U-Boot bootloader in the ALB[4], which we build and test with our patched version of the Linaro GCC 6.3.1 2017.05 toolchain for ARM 64-bit, with sources available on [5].
