[PATCH qemu v6 0/4] hw/cxl/cxl-mailbox-utils: Add feature commands, device patrol scrub control and DDR5 ECS control feature

[Jonathan Cameron via <qemu-devel@nongnu.org>]

I believe this is ready to merge (I was holding it until DCD was
in place and that is upstream now)

Changes since v5:
- Include Gregory's patch to bring forward the renames.  Not strictly
  needed here, but a sensible change and it makes reordring my
  CXL staging tree a lot simpler.

Based-on: [PATCH qemu 0/4] hw/cxl: Add support for scan media
Message-id: 20240705120643.959422-1-Jonathan.Cameron@huawei.com

Add support for the feature commands, device patrol scrub control and
DDR5 ECS control features.

CXL spec 3.1 section 8.2.9.6 describes optional device specific features.
CXL spec 3.1 section 8.2.9.9.11.1 describes the device patrol scrub control
feature.
CXL spec 3.1 section 8.2.9.9.11.2 describes the DDR5 Error Check Scrub (ECS)
control feature.

This series is one of the test vehicles for the support of RAS feature
control in Linux and having it upstream would be useful to support that work.
There are also a lot more 'features' using the feature infrastructure
that are dependent on the first 2 patches.
