The NXP S32 QSPI controller acts as an interface to up to two serial flash memory devices, each with up to eight bidirectional data lines, depending on the platform. It is based on a LUT enginee to interface through commands with different memory types including flash NOR and Hyperram. This patch adds support for the QSPI in S32K344 which supports a single memory device (side A) with up to four bidirectional data lines and SDR only. Nevertheless, the memory controller is implemented flexible enough to be extended to support more feature-rich QSPI blocks. Signed-off-by: Manuel Argüelles <manuel.arguelles@nxp.com> |

The Zephyr OS is based on a small-footprint kernel designed for use on resource-constrained systems: from simple embedded environmental sensors and LED wearables to sophisticated smart watches and IoT wireless gateways. The Zephyr kernel supports multiple architectures, including ARM (Cortex-A, Cortex-R, Cortex-M), Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V, SPARC, MIPS, and a large number of `supported boards`_. .. below included in doc/introduction/introduction.rst Getting Started *************** Welcome to Zephyr!
