Piyush Patle 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.

Bowen Wang 51d6e8f49e virtio/vhost: assign the virtio/vhost_drvier to device->priv before probe
So the driver can get the driver pointer by vdev/hdev->priv,
and later vdev/hdev->priv can be used to store other data such as the
virtio/vhost drivers' private data.

wanggang26 0e7e7c4ee6 rpmb: add virtio rpmb support
The RPMB partition cannot be accessed via standard block layer, but by a set of specific commands: WRITE, READ, GET_WRITE_COUNTER, and PROGRAM_KEY. Such a partition provides authenticated and replay protected access, hence suitable as a secure storage.

wangbowen6 9aa57b6c53 virtio: add virtio framework in NuttX
1. virtio devics/drivers match and probe/remote mechanism;
2. virtio mmio transport layer based on OpenAmp (Compatible with both
   virtio mmio version 1 and 2);
3. virtio-serial driver based on new virtio framework;
4. virtio-rng driver based on new virtio framework;
5. virtio-net driver based on new virtio framework
   (IOB Offload implementation);
6. virtio-blk driver based on new virtio framework;
7. Remove the old virtio mmio framework, the old framework only
   support mmio transport layer, and the new framwork support
   more transport layer and this commit has implemented all the
   old virtio drivers;
8. Refresh the the qemu-arm64 and qemu-riscv virtio related
   configs, and update its README.txt;

New virtio-net driver has better performance
Compared with previous virtio-mmio-net:
