Re: VM-friendly 64-bit ARM binaries that use Linux bootloader & VirtIO support?

Hi Chris --

Here's a kernel that implements the Linux boot protocol and includes a 
Linux Arm64 kernel image header, along with an initrd image:

Take care,
Jared

(I assume such boot pieces already exist for NetBSD on 64-bit Intel; if they do, how are they named? I’d be happy to try that on Macs with Intel CPUs as well, of course.)
