[PATCH v4 06/80] vl.c: move -m parsing after memory backends has been processed |
Date: |

It will be possible for main RAM to come from memory-backend
and we should check that size specified in -m matches the size
of the backend and [MachineState::]ram_size also matches
backend's size.
However -m parsing (set_memory_options()) happens before backends
are intialized (object_create_delayed()) which complicates it.
Consolidate set_memory_options() and assigning parsed results to
current_machine after backends are initialized, so it would be
possible access the initialized backend instance to compare
sizes.
This patch only consolidates scattered places touching ram_size
within vl.c. And follow up patch will integrate backend handling
to set_memory_options().
