Hi there,

We need support for Cortex-A55, yet another ARMv8-A architecture and are currently working on this.

Our idea is to leverage the current GCC/ARM_CA53_64_BIT_SRE port by renaming it.
Furthermore, it would seem that even the ARMv9-A architectures could be supported with the same port[1].
As a solution, we have come up with renaming the latter to GCC/AARCH64_SRE and use the same for Cortex-A55. It should also work for Cortex-A78AE.

@johnrhen : is this approach reasonable?
@Hunter-Phipps : stay tuned for this upcoming change that we will first push on our fork repo[2] while the discussion is ongoing here.

Thanks,
Stephane.
