283742e29c drivers/rpmsg: Fix typo rpmsg_device_destory -> rpmsg_device_destroy
Rename rpmsg_device_destory() to rpmsg_device_destroy() to fix a
spelling error in the function name.  The function is declared in the
private header drivers/rpmsg/rpmsg.h and used only within the
drivers/rpmsg/ subsystem (rpmsg.c, rpmsg_virtio.c,
rpmsg_router_edge.c, rpmsg_port.c), so there is no public API or
ABI impact.

0dccc8ba21 include/debug.h: Move to include/nuttx/debug.h
debug.h is a NuttX-specific, non-POSIX header. Placing it in the
top-level include/ directory creates naming conflicts with external
projects that define their own debug.h.
This commit moves the canonical header to include/nuttx/debug.h,
following the NuttX convention for non-POSIX/non-standard headers,
and updates all in-tree references.

A backward-compatibility shim is left at include/debug.h that
emits a deprecation #warning and re-includes <nuttx/debug.h>,
allowing out-of-tree code to continue building while migrating.

877a9af2d1 rpmsg_virtio/rptun: support fallback cpuname when VIRTIO_RPMSG_F_CPUNAME not set
When the VIRTIO_RPMSG_F_CPUNAME feature is not negotiated, the driver
previously would crash due to DEBUGASSERT. This commit adds support
for a fallback mechanism:

1. Add rpmsg_virtio_probe_cpuname() API that accepts an optional cpuname
   parameter to be used when VIRTIO_RPMSG_F_CPUNAME is not available.

2. Modify rptun driver to pass the cpuname from rptun device config
   to rpmsg_virtio_probe_cpuname().

3. Refactor rptun device register/unregister to prioritize RPMSG device
   handling before other virtio device types.

This ensures the system works correctly in scenarios where the remote
side does not support the VIRTIO_RPMSG_F_CPUNAME feature.

f56ea30479 drivers/rpmsg: refactor internal APIs to private header
Move rpmsg internal APIs from public header include/nuttx/rpmsg/rpmsg.h
to private header drivers/rpmsg/rpmsg.h. These APIs are only used within
the rpmsg driver implementation and should not be exposed to external
modules.

Moved APIs:
- rpmsg_modify_signals()
- rpmsg_ns_bind() / rpmsg_ns_unbind()
- rpmsg_device_created() / rpmsg_device_destory()
- rpmsg_register() / rpmsg_unregister()

aa567d43f6 drivers/rpmsg: fix struct alignment issue by removing zero array member
This commit fixes a memory alignment issue in the rpmsg subsystem.
The previous implementation used a flexible array member (rdev[0])
in struct rpmsg_s, but due to automatic 8-byte padding, rpmsg->rdev
could differ from the transport layer's rdev address (e.g.,
rpmsg_virtio->rvdev.rdev), causing potential memory corruption.

Changes:
- Remove rdev[0] flexible array member from struct rpmsg_s
- Add rpmsg_get_rdev_by_rpmsg() inline helper to calculate rdev
  address as (rpmsg + 1), ensuring correct pointer arithmetic
- Update all rpmsg->rdev references to use the new helper function
- Fix rpmsg_virtio_notify_wait() to use correct container_of macro

ab47465dd5 drivers/rpmsg: add get_local_cpuname to rpmsg ops
Add get_local_cpuname to the rpmsg framework ops to support communicate
with the same remote core with multi rpmsg transport.

Some rpmsg services will send local cpu name to remote core and then let
remote core to connect local core by using this cpu name, when there are
multi rpmsg channels with same remote core, the remote core may connect
to incorrect core, so use the error rpmsg channel.

For example, there are two rpmsg channels between ap and audio:

ap core                     audio core
 [ap1] <-- rpmsg virtio1 --> [audio1]
 [ap2] <-- rpmsg virtio2 --> [audio2]

When we want to use the rpmsg virtio1 to communicate, ap core may send
local cpuname "ap2" to audio, so the audio core use remote cpu "ap2" to
connect with ap, and resulting in the use of incorrect rpmsg channel.

af0bde8bca rpmsg virtio: add rpmsg virtio wrapper support
Rpmsg VirtIO is a virtio transport implementation for Rpmsg, and
it's different to the rptun framework.

rpmsg_virtio.c implements the rpmsg virtio transport layer by itself
to avoid use the remoteproc implementation in OpenAMP to save code
size, so it can be treated as a lightweight version of rptun.
Therefore, rpmsg_virtio.c only support the communication feature and
do not support contoll the life cycle of the remote core.
But benefit by it's small footprint, it can be used in the chips with
small flash.
