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].
Changes in v2:
* Update the entry in fsl.yaml to apply to all S32V234 based boards;
* Add chosen node to dts, with a 'stdout-path' property for earlycon;
* Remove linflex_verify_port(), because it was only called from
uart_set_info(), which was going to always fail at the "baud_base < 9600"
check, as we are not using uartclk from uart_port yet;
* Fix compatible string used in OF_EARLYCON_DECLARE.
