Is there an easy to follow documentation or commit that shows how to port
gdbserver for baremetal ?

I'm afraid there isn't. I suppose you are talking about actually coming
up with a debugging stub that implements the most minimal set of remote
protocol packets, right? Not "gdbserver" itself, which is always OS-hosted.
From the documentation here...
https://sourceware.org/gdb/onlinedocs/gdb/Overview.html#Overview
... it says:
"At a minimum, a stub is required to support the ‘?’ command to tell GDB
the reason for halting, ‘g’ and ‘G’ commands for register access, and
the ‘m’ and ‘M’ commands for memory access. Stubs that only control
single-threaded targets can implement run control with the ‘c’
(continue) command, and if the target architecture supports
hardware-assisted single-stepping, the ‘s’ (step) command. Stubs that
support multi-threading targets should support the ‘vCont’ command. All
other commands are optional."
But the above may be stale at this point.
