I'm working on a BSP that features the Reesas RZ/G2L & RZ/V2L CPUs which have a Cortex-A55 core onthe Arm8.2 architecture. I don't see it listed under https://www.denx.de/wiki/view/ELDK-5/WebHome#Section_1.4. and was wondering if there's a way to use ELDK for this Aarch64 architecture at all?

I would recommend you use Buildroot https://buildroot.org/ to build a cross compiler and pretty much everything else you need to boot and run linux (or your custom code) on your CPU. It takes a bit to configure it and a while to build from scratch, but it works very well. Buildroot makes building a cross compiler extremely simple. Building a whole (linux based) system is complicated only because there are many, many choices to make - the actual building is trivial.

Instead of Buildroot, I have now built a distribution that I can use on the platform with Yocto and it does give me U-Boot as well as an SDK with it as well.

Thanks!
