Support moving PRIVILEGED_DATA via an optional MPU wrapper:

  • User can define portMOVE_PRIVILEGED_DATA as a section attribute to move the PRIVILEGED_DATA section arbitrarily.
  • Allows critical data to be placed in port-specific location for improved performance, notably for cache-coherent SMP.
  • Does not require enabling the full MPU wrappers.

Increment Partner-Supported-Ports submodule to the latest commit

Passed regression testing with 100+ Xtensa configurations (SMP and single-core)
