Original armvirt target is now subtarget 32. Other than that the built
result should remain the same as before
Besides old features already available with arm64, the new armvirt/64
subtarget will also have those features originally enabled for
armvirt/32 with commit 44ecfc2 ("armvirt: new target")

The multi-platform ARMv8 target can be used with QEMU:
|
|
|
|
qemu-system-aarch64 -machine virt -cpu cortex-a57 -nographic \
|
|
-kernel lede-armvirt-64-Image-initramfs \
