The UEFI loading mode in loongarch is very different from that in other architectures:loongarch's UEFI code is in rom, while other architectures' UEFI code is in flash. loongarch UEFI can be loaded as follows: -machine virt,pflash=pflash0-format -bios ./QEMU_EFI.fd Other architectures load UEFI using the following methods: -machine virt,pflash0=pflash0-format,pflash1=pflash1-format loongarch's UEFI loading method makes qemu and libvirt incompatible when using NVRAM, and the cost of loongarch's current loading method far outweighs the benefits, so we decided to use the same UEFI loading scheme as other architectures.
