BBRAM File Backend
""""""""""""""""""
BBRAM can have an optional file backend, which must be a seekable
binary file with a size of 36 bytes or larger. A file with all
binary 0s is a 'blank'.
To add a file-backend for the BBRAM:
.. code-block:: bash
-drive if=pflash,index=0,file=versal-bbram.bin,format=raw
To use a different index value, N, from default of 0, add:
.. code-block:: bash
-global xlnx,bbram-ctrl.drive-index=N
eFUSE File Backend
""""""""""""""""""
eFUSE can have an optional file backend, which must be a seekable
binary file with a size of 3072 bytes or larger. A file with all
binary 0s is a 'blank'.
To add a file-backend for the eFUSE:
.. code-block:: bash
-drive if=pflash,index=1,file=versal-efuse.bin,format=raw
To use a different index value, N, from default of 1, add:
.. code-block:: bash
-global xlnx,efuse.drive-index=N
.. warning::
In actual physical Versal, BBRAM and eFUSE contain sensitive data.
The QEMU device models do **not** encrypt nor obfuscate any data
when holding them in models' memory or when writing them to their
file backends.
Thus, a file backend should be used with caution, and 'format=luks'
is highly recommended (albeit with usage complexity).
Better yet, do not use actual product data when running guest image
on this Xilinx Versal Virt board.
