GIC redistributor on Some platform are connected to a non-coherent downstream interconnect, it need to use Non-cahable and Non-shareable access atttributes to access external memory. And also flush the data cache after CPU update related memory. Signed-off-by: Jiafei Pan <Jiafei.Pan@nxp.com>
In case of ITS is enabled, need to include LPI in the total number of irq. Signed-off-by: Jiafei Pan <Jiafei.Pan@nxp.com>
GIC redistribute on i.MX 95 is DMA noncoherent, so enable CONFIG_GIC_V3_RDIST_DMA_NONCOHERENT. Signed-off-by: Jiafei Pan <Jiafei.Pan@nxp.com>
GIC ITS depends on kernel heap, so move GIC initialize to be behind of heap which initialization priority is CONFIG_KERNEL_INIT_PRIORITY_OBJECTS (it is 30 by default). MU mailbox and SCMI objects depend on GIC, so set their init priority to be same with GIC, the initialization sequence decided by the dts dependency although they use the same init priority. Signed-off-by: Jiafei Pan <Jiafei.Pan@nxp.com>
Add imx95_evk support, as hardware limication, it only has 832 LPIs. Signed-off-by: Jiafei Pan <Jiafei.Pan@nxp.com>
Tmp patch to depend on hal_nxp PR 571. Signed-off-by: Jiafei Pan <Jiafei.Pan@nxp.com>
It could use GIC ITS as MSI controller on Cortex-A Core, so added GIC ITS MSI support for NETC drivers. Signed-off-by: Jiafei Pan <Jiafei.Pan@nxp.com>

Add NETC block driver, it could do some block memory region MMIO mapping and also so dome block initialization, moved some netc related configuration form board_init() to block driver so that it could be reused between different platforms, although some configuration is different for different platform, but put all NETC related code in the same driver to make it easier to be maintained. Signed-off-by: Jiafei Pan <Jiafei.Pan@nxp.com>
Added MMIO memory mapping for NETC MDIO driver. Signed-off-by: Jiafei Pan <Jiafei.Pan@nxp.com>
Added MMIO memory mapping support in nxim_imx_netc driver as need to do MMU mapping for Cortex-A Core, but the update is also feasible for Cortex-M Core. Signed-off-by: Jiafei Pan <Jiafei.Pan@nxp.com>
In order to support MMU mapping on Cortex-A core, added MMIO mapping support in imx_netc_psi driver. Signed-off-by: Jiafei Pan <Jiafei.Pan@nxp.com>
i.MX 95 has no NETC switch, so disable it on this platform. Signed-off-by: Jiafei Pan <Jiafei.Pan@nxp.com>
Update NETC device nodes according to NETC driver update: 1. Added NETC block control device node to handle block control initialization in netc block driver. 2. Added "nxp,imx-netc" compatible for netc driver to handle MMIO mapping in the driver. 3. Added all memory region in MMIO reg propertiy to let driver to handle MMIO mapping for all memory region. 4. Move MMIO device node out of netc device node to decouple the device initialization priority, so that MMIO could be initialized before netc driver initialization. Signed-off-by: Jiafei Pan <Jiafei.Pan@nxp.com>

Added SCMI power dts node. Signed-off-by: Jiafei Pan <Jiafei.Pan@nxp.com>
Power up NETCMIX and configure netc clock in soc_init(). Signed-off-by: Jiafei Pan <Jiafei.Pan@nxp.com>
Removed overlay and enabled these nodes in board dts directly as it is not be valid unless CONFIG_NETWORKING is enabled. Signed-off-by: Jiafei Pan <Jiafei.Pan@nxp.com>

v3: enlarge networking stack size to avoid net_mgmt thread crash. |

Added NETC PSI0 support on the i.MX 95 EVK board for A55 platform. Signed-off-by: Jiafei Pan <Jiafei.Pan@nxp.com>
The issue is caused by default stack size 1500 bytes of NET_RX_STACK_SIZE is to small for ARM64 platform, then the stack of net_rx thread is overflow and break the net_mgmt thread's stack, as a result net_mgmt thread is crashed. So this patch will enlarge all the stack size of net stack threads. Signed-off-by: Jiafei Pan <Jiafei.Pan@nxp.com>
Add i.MX 95 EVK A55 support for zperf sample. Signed-off-by: Jiafei Pan <Jiafei.Pan@nxp.com>

This PR is to enable NETC support on i.MX 95 A55.
Actually it includes two main update, one is to enable GIC ITS on A55, the other one is to enable NETC support on Cortex-A core, so I created two PR, the first part for GIC update is in PR #92346, and this PR is for NETC driver related update, so this PR is based and depends on #92346
This PR also depends on hal PR: zephyrproject-rtos/hal_nxp#571
