From 7e47e15c8b47ac866e8f07998276b01e612a360a Mon Sep 17 00:00:00 2001 From: Tong Ho Date: Thu, 16 Sep 2021 22:23:58 -0700 Subject: hw/arm: xlnx-zcu102: Add Xilinx BBRAM device Connect the support for Xilinx ZynqMP Battery-Backed RAM (BBRAM) The command argument: -drive if=pflash,index=2,... Can be used to optionally connect the bbram to a backend storage, such that field-programmed values in one invocation can be made available to next invocation. The backend storage must be a seekable binary file, and its size must be 36 bytes or larger. A file with all binary 0's is a 'blank'.
