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 <[email protected]>

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.

In order to support MMU mapping on Cortex-A core, added MMIO mapping support in imx_netc_psi driver. Signed-off-by: Jiafei Pan <[email protected]>
i.MX 95 has no NETC switch, so disable it on this platform. Signed-off-by: Jiafei Pan <[email protected]>
As reg property is not used by the driver and there is no proper address could be assigned to it, so remove it. Signed-off-by: Jiafei Pan <[email protected]>
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. 3. Added all memory region in MMIO reg propertiy to let driver to handle MMIO mapping for all memory region.

Power up NETCMIX and configure netc clock in soc_init(). Signed-off-by: Jiafei Pan <[email protected]>
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 <[email protected]>
Added NETC PSI0 support on the i.MX 95 EVK board for A55 platform. Signed-off-by: Jiafei Pan <[email protected]>
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 <[email protected]>

v4: moved pci config memory region from netc dts node to each psi dts node as some platform such as imx943 can't use a continues region to cover all pci config region for all PSI's, it is also aligned with MDIO which we put config region in itself dts node. so that we could remove reg property from netc dts node. |

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
