From: Ciprian Marian Costea <ciprianmarian.costea@oss.nxp.com> This series introduces initial device tree support for the NXP S32N79 automotive SoC and its Reference Design Board (RDB). The S32N79 is an automotive-grade system-on-chip featuring eight Arm Cortex-A78AE cores organized in four dual-core clusters. It is designed for high-performance networking and gateway applications vehicle architectures [1] Hardware features included in this initial support: - 8x Arm Cortex-A78AE cores (4 clusters of 2 cores each) - 32GB DRAM Memory. 28GB are usable and 4GB are reserved for ECC logic - Three-level cache hierarchy (L1/L2 per core, L3 per cluster) - GICv3 interrupt controller with ITS - SMMUv3 for IOMMU support - Generic Timer - IRQ steering controller - PL011 UART controllers - uSDHC controller This series also includes the necessary driver updates: - sdhci-esdhc-imx: Add S32N79 uSDHC controller support - irq-imx-irqsteer: Add S32N79 IRQ steering support - irqchip Kconfig: Add ARCH_S32 dependency for IMX_IRQSTEER Future patches will add support for additional peripherals such as networking controllers, PCIe, and other IP blocks.
