The ARM libdebugger has support to use memory mapped registers. It is determined by the ROM and then rtems_debugger_arm_debug_registers. I think the code currently assume CP14 instructions but I think that could be made conditional where needed? Are these builds of Cortex-M processors able to support libdebugger? I have been rejecting changes like this unless there is a reason it cannot be made to work. Are there reasons it cannot be made to work?
