This patch series introduces remoteproc support for NXP i.MX8M and i.MX93
platforms. Most of the i.MX-specific logic is ported from the Linux kernel to
ensure compatibility and maintainability.
The existing bootaux command in U-Boot only supports loading raw binary images.
However, this approach fails when the remote processor firmware contains
sections that must be loaded into both TCM and DDR. To address this limitation,
need to use remoteproc framework ELF loader, enabling proper loading of
segmented firmware images.
Patch Summary:
Patches 1–2: Import memcpy_io and memset_io from the Linux kernel and enable
them in the remoteproc subsystem.
which CPU arch, you are using. I assume this is ARM-64 then I see
already defined in
https://elixir.bootlin.com/u-boot/v2025.10/source/arch/arm/include/asm/io.h#L471
Patches 3–11: Add platform-specific remoteproc support for i.MX8M and i.MX93.
Patch 6: Temporarily adds Cortex-M nodes to x-u-boot.dtsi since they are not
yet available in the upstream Linux device tree. These nodes can be
removed once they are merged upstream.
NXP internal R-b tags are kept, because the patches are directly
cherry-picked from NXP LTS tree.
