Use Case
~~~~~~~~

User acquires a machine running ARM Linux version 3.x, with u-boot
and dtb in a read only flash partition. The board boots and works just
fine. However, for his application, the user requires a new kernel
feature that appeared in version 3.y where y > x. He compiles the new
kernel, and it also works.

Thanks,
Richard
