@iuliana-prodan @dbaluta I've merged the HAL and updated your Zephyr side PR. @doki-nordic can we get your review on this PR? |

This PR depends on some updates on openamp_rsc_table sample: #84170 because for i.MX8ULP we have different memory maps for device (DSP side) and driver (Cortex A side). Therefore the shared memory between them has different values and we need to convert the addresses. |

Fix the following compile warning: "Warning (unique_unit_address_if_enabled): /cpus/cpu@0: duplicate unit-address (also used in node /cpus/interrupt-controller@0)" Signed-off-by: Iuliana Prodan <[email protected]>
Add resource_table section in linker script for i.MX8ULP, for inter-process communication. Signed-off-by: Iuliana Prodan <[email protected]>
Add mailbox node used for inter-process communication. Signed-off-by: Iuliana Prodan <[email protected]>
Add the dts and config overlay for imx8ulp_evk//adsp to have the openamp_rsc_table sample working on HiFi4 DSP from i.MX8ULP. Since openamp_rsc_table sample uses IPM API and i.MX8ULP has a mbox driver for messaging unit, we need a mailbox node. This will load the ipm_mbox driver that exposes the IPM interface while using a MBOX driver in the back-end. On i.MX8ULP, for DSP, the driver physical address is different than the device physical address, therefore enable CONFIG_OPENAMP_ADDR_TRANSLATION and add "zephyr,ipc_shm_translation" node.
