From 238ea0e311560eebc5a531cad6adabc66224eb2c Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Wed, 19 Feb 2020 11:09:00 -0500 Subject: [PATCH] arm/omap_sx1: 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. PS: while at it add check for user supplied RAM size and error out if it mismatches board expected value.
