[PATCH 39/86] arm:xlnx-zcu102: use memdev for RAM |
Date: |
Tue, 31 Dec 2019 14:03:23 +0100 |
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.
