It is a bit weird that qemu-system-aarch64 runs with a cortex-a15 model tbh, as cortex-a15 is not capable of aarch64.
No, but qemu-system-aarch64 is capable of 32-bit emulation (because most 64-bit cpus retain 32-bit mode). It takes no extra effort to run cortex-a15 than it does a cortex-a57.
I have wondered if we should have just one qemu-system-arm that does it all and drop the separate qemu-system-aarch64 -- or vice versa. But we've had the separation around so long I'm sure someone would be confused.
