From 783dbab19fb79eee2b59c23043ca555d996cb91b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Thu, 19 Aug 2021 18:34:22 +0200 Subject: hw/dma/xlnx-zdma Always expect 'dma' link property to be set MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Simplify by always passing a MemoryRegion property to the device. Doing so we can move the AddressSpace field to the device struct, removing need for heap allocation. Update the Xilinx ZynqMP / Versal SoC models to pass the default system memory instead of a NULL value.
