AN15075 Patch can't be applied

oedze — Tue, 01 Sep 2026 10:22:19 GMT

The relativly new user manual AN15075 metions the file 0001-add-AHAB-check-for-imx
remote-proc-process.patch

Which i found in the AN15075SW.zip.

This patch files applies the following 3 lines:

+#ifdef CONFIG_IMX_REMOTEPROC_AHAB +#include <linux/firmware/imx/ele_base_msg.h> +#include <linux/firmware/imx/se_fw_inc.h> +#endif

drivers/remoteproc/imx_rproc.c from linux-imx

but tthe file linux/firmware/imx/se_fw_inc.h doesn't exist (anywhere on the internet)

And the file ele_base_msg is not placed at that location.

I am working on the linux-imx lf-6.18.y branch https://github.com/nxp-imx/linux-imx/tree/lf-6.18.y
I couldn't find it on the 6.6 or 6.12 either.

To what version of linux-imx should this patch be applied?

P.S. If you add the patch and disable

CONFIG_IMX_REMOTEPROC_AHAB
The linux-imx won't build either because some properties stopped existing because some of the code is guarded under a #ifdef but not all.

Did some more digging:

This patch seems to add these files: [PATCH v4 6/7] firmware: imx: add driver for NXP EdgeLock Enclave
But it was reapplied differently in this commit: LF-13910: firmware: imx: add driver for NXP EdgeLock Enclave · nxp-imx/linux-imx@0eff402

Apply AN15075SW’s kernel patch to lf-6.6.36-2.1.0 / BSP lf-6.6.36 .

$ git clone https://github.com/nxp-imx/linux-imx.git

$ git checkout -b lf-6.6.36-2.1.0 lf-6.6.36-2.1.0

Do not expect it to apply cleanly to lf-6.18.y ; it must be forward-ported.

If forward-porting, fix both the include paths and the Kconfig guards. Your PS is consistent with a partial guard bug: disabling CONFIG_IMX_REMOTEPROC_AHAB should leave the existing remoteproc path buildable, but the AN patch appears to leave some non-AHAB code dependent on definitions or fields introduced only inside #ifdef CONFIG_IMX_REMOTEPROC_AHAB .

Is there any change NXP will update the patch for Yocto Wrynose (with linux 6.18)?

The patch we implemented at that time was merely a proof of concept, and the software team did not agree to merge it into the upstream repository.
So it's just a reference implementation.
The subsequent porting was not continued.

Is modifying the remoteproc code to use the ELE firmware still the recommended approach to enable AHAB on the second core?

Yes.
