This implements the Xilinx Versal eFuse, an one-time field-programmable non-volatile storage device. There is only one such device in the Xilinx Versal product family. This device has two separate mmio interfaces, a controller and a flatten readback. The controller provides interfaces for field-programming, configuration, control, and status. The flatten readback is a cache to provide a byte-accessible read-only interface to efficiently read efuse array. Co-authored-by: Edgar E.
