The "firmware missing" message is a bit misleading. The SDMA unit has
ROM firmware which can be patches if you install a separate firmware. So
yes, it is missing, but it isn't necessarily a problem. The kernel
message should be fixed.

The IPU is a complex component, and our first attempt to break it into
several components still has issues and doesn't fit the DRM framework's
requirements well (one of the reasons we pushed it into staging first).

The whole issue has been discussed at the ARM kernel summit in Edinburgh
recently, and Russell King is working on patches to fulfill the DRM
maintainers' requirements.

Please be a bit patient, the whole issue is being worked on.

Follow alkml and drm-devel.
