[PATCH v6 0/5] arm64: Add initial support for NXP S32N79 SoC

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.

v6 -> v5
- Patches 2 and 4 from v5 have been applied, hence dropped from this series
- Removed redundant zero initialization in imx_data struct

v5 -> v4
- Squashed irqsteer 'Kconfig' changes with the actual driver updates.
- Fixed tabular layout in the irq-imx-irqsteer driver
- Added received 'Reviewed-by' and 'Acked-by' tags from V4.

v4 -> v3
- Added missing Signed-of-by's from one commit removed in v3 by mistake

v3 -> v2
- Split S32N79 SoC dtsi into separate standalone commit
- Renamed a memory node in the S32N79 board dts
- Fixed IRQ STEER DT-Bindings support for S32N79 addition
- Updated S32N79 usdhc driver support commit message

v2 -> v1
- added driver changes required for S32N79 uSDHC support
- added driver changes required for S32N79 IRQ_STEER support
- updated commit message for uSDHC dt-bindings
- implemented fixes for 'dt-format' tool findings on newly added S32N79 dts files
