[PATCH v3 0/9] hw/nvram: hw/arm: Introduce Xilinx eFUSE and BBRAM

[Tong Ho]

This series implements the Xilinx eFUSE and BBRAM devices for
the Versal and ZynqMP product families.

Furthermore, both new devices are connected to the xlnx-versal-virt
board and the xlnx-zcu102 board.

See changes in docs/system/arm/xlnx-versal-virt.rst for detail.
