Yocto 4.2 Mickledore-based embedded Linux

What is the benefit? Why is this valuable?
The market expects Qt to support latest Yocto versions. Boot to Qt 6.6.0 will be based on Yocto 4.2 Mickledore. Mickledore release is scheduled for April 2023.  Update relevant meta layers so that supported targets build agaist Mickledore.
What are common use cases?
Mickledore is to be used for B2Qt use cases for easy embedded development.
