I updated my git and browsed the log records, the only commits of Michael were
from Mov 3, and apparently did not include this functionality.

you mean Michael's code is not yet in the master branch?

my intent is to isolate the Cortex-M code from the existing ARM implementation,
practically it should be a fresh start of the Cortex-M code, with a NVIC that
no longer inherits from GIC.
if you plan to further maintain the existing code, fain, but for me it is a bit
too messy and I cannot rely on it, I need a clean implementation of the system
peripherals, with properly processed exceptions.
if Michael code is not in, when do you think it will be, so I can make a
decision to either continue to patch the existing code or to redo the system
code?
