Add a frontend for the blkmap subsystem. In addition to the common block device operations, this allows users to create and destroy devices, and map in memory and slices of other block devices.
With that we support two primary use-cases:
Being able to "distro boot" from a RAM disk. I.e., from an image where the kernel is stored in /boot of some filesystem supported by U-Boot.
Accessing filesystems not located on exact partition boundaries, e.g. when a filesystem image is wrapped in an FIT image and stored in a disk partition.
