Attached is a patch to add native linux support for gdb including
cache target support.

The patch has been sanity tested on a linux instance running on qemu (runqemu).

Some commonly used debugger functions such as breakpoints, step, next,
finish, print were tested to be working.

The original sources for the patch come from Xilinx/AMD Yocto git
repository (2025.2)

These went through some editing as well as some refactoring.
