From ab74e543112957696f7c79b0c33ecebd18b52af5 Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Wed, 19 Feb 2020 11:09:41 -0500 Subject: [PATCH] ppc/spapr: use memdev for RAM MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit memory_region_allocate_system_memory() API is going away, so replace it with memdev allocated MemoryRegion. The later is initialized by generic code, so board only needs to opt in to memdev scheme by providing MachineClass::default_ram_id and using MachineState::ram instead of manually initializing RAM memory region.
