[PATCH 0/4] NVMe: Add SPDM over the storage transport support

[Wilfred Mallawa <wilfred.opensource@gmail.com>]

From: Wilfred Mallawa <wilfred.mallawa@wdc.com>

This series extends the existing SPDM support in QEMU to support the DSP0286
SPDM Storage Transport [1] for NVMe. SPDM Storage Transport uses the NVMe
Admin Security Send/Receive commands, as such, support for these commands have
also been added.

With the addition of a new `spdm-trans` CLI argument for NVMe controllers,
users can specify `spdm_trans=nvme` or `spdm_trans=doe`. This allows for the
selection of the SPDM transport. The `doe` option is the current default,
`nvme` would select SPDM Storage Transport for the controller, where SPDM
communication happens over the NVMe Admin Security Send/Receive commands.

Support for DSP0286 already exists in `libspdm` [2] and support for the QEMU
SPDM server is being upstreamed for `spdm-utils` [3]. This series was tested by
using `spdm-utils` as the qemu SPDM server with SPDM Storage Transport support
built with `libspdm` v3.8.0, and `spdm-utils` also as the SPDM requester.
