…e configuration parsing
linux-aarch64-a1000-smp8.tomlandlinux-aarch64-rk3588-smp8.toml,Changed the mapping type of
memory_regionsand removed some redundantpassthrough_devicesconfigurations.Added
VmMemMappingType::MapReservedbranch processing logic to support mapping memory regions with the same physical address.Refactored the
parse_passthrough_devices_addressfunction to prioritize the device address preset in the configuration file.If not set, it will fall back to parsing from the device tree, improving flexibility and compatibility.
