We already have some physical mainboards for AArch64. However, we don’t have the support of QEMU/AArch64 yet. ARM-based chips nowadays become popular especially in embedded systems so this movement would spread to 64-bit ARM architectures. Supporting QEMU/AArch64 in the coreboot project would be helpful for developers with compatibility testing. It also would help to make sure that changes to architecture code don’t break current implementations.
The goal of this project is that we can use the following command:
$ qemu-system-aarch64 -bios build/coreboot.rom -machine virt -cpu cortex-a53
