Alexey Brodkin Jan. 6, 2024, 9:20 p.m. UTC 
To simplify ramp-up with Linux on 32-bit  ARC HS58 & 64-bit ARC HS68
processors we introduce 2 defconfigs with instructions on how to build
embedded Linux image for them and how to run resultoing image.

As with earlier images for simulated platforms it's possible to
use the same image with either proprietary Synopsys nSIM simulator,
QEMU or even with real FPGA-based prototyping platform called HAPS.

That not only convenient, but also helps to work on observed issues,
i.e. run the same image on so very different platforms and see if
earlier observed problem is still there. That way we may easily
verify various platforms against each other.

For example, if one image works on nSIM & FPGA but doesn't work
on QEMU, it's clear something needs to be fixed in QEMU.

But if exactly the same though unexpected behavior is observed on all
the platforms, we may say with quite some confidence, that we're dealing
with a pure software or tools issue.
