Support for Cortex-A55

[Alyosha Shevandin]

I would like to know what is the status of Cortex-A55 support. I had read all relevant messages in this mail list and the documentation and still can not understand if it is supported.

For instance, this documentation states that there Cortext-A55 is supported by generic virtual platform (virt): https://qemu.readthedocs.io/en/latest/system/arm/virt.html

The below call:

qemu-system-aarch64 -nographic -machine virt,secure=on -cpu cortex-a55 -smp clusters=1,cores=1 -m 1024 -bios ../bl1.bin -d unimp -semihosting-config enable=on,target=native

fails with error:

qemu-system-aarch64: unable to find CPU model 'cortext-a55'

The qemu-system-aarch64 binary is build from the top of the master branch.

I’m also not able to find any reference to Cortext-A55 in the sources. For instance target/arm/cpu64.c, aarch64_cpus

does not contain any reference to Cortex-A55.
