To avoid using -drive as much as possible convert PFLASH to use
-blockdev as well.
Since -blockdev is not enabled yet use the following qemu namespace XML
override to enable it for testing:
<domain type='kvm'
xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
...
<qemu:capabilities>
<qemu:add capability='blockdev'/>
</qemu:capabilities>
</domain>

qemu: command: Extract formatting of -drive for pflash

qemu: domain: Introduce helper to convert <loader> into
virStorageSource
qemu: command: Build -blockdev-s for backing of pflash
qemu: command: Build the 'pflash' drives via -machine
qemu: Instantiate pflash via -machine when using blockdev

New subject: [libvirt] [PATCH 1/6] qemu: command: Extract formatting of -drive for pflash
Extract the old way to instantiate pflash devices to hold the firmware
via -drive to a separate function so that it can later be conditionally
disabled when -blockdev will be used.

New subject: [libvirt] [PATCH 3/6] qemu: domain: Introduce helper to convert <loader> into virStorageSource
Add a helper which will covert the PFLASH code file and variable file
into the virStorageSource objects stored in private data so that we can
use them with -blockdev while keeping the infrastructure to determine
the path to the loaders intact.
This is a temporary solution until we will want to do snapshots of the
pflash where we will be forced do track the full backing chain in the
XML.
In the meanwhile just convert it partially so that we can stop using
-drive.

New subject: [libvirt] [PATCH 6/6] qemu: Instantiate pflash via -machine when using blockdev

Install the convertor function which enables the internals that will
use
-blockdev to make qemu open the firmware image and stop using -drive.

Since -blockdev is not enabled yet use the following qemu namespace XML
override to enable it for testing:
<domain type='kvm'
xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
...
<qemu:capabilities>
<qemu:add capability='blockdev'/>
</qemu:capabilities>

There ought to be a file added to qemuxml2argvtest to validate the
new -blockdev syntax for pflash. Maybe you have it further down in
your queue of pending blockdev patches ? If not just send a followup
to add a test, no need to repost this whole series.

I've finally come to the patch in the blockdev series which adds
testing coverage for pflash with -blockdev.
