For debug usage is added backend for memory window. Coredump is being dumped in raw data. It needs to be converted to ACSII for later analysis. Data is written to telemetry slot in memory window which is a space where is located all debbug information. Signed-off-by: PawelX Dobrowolski <pawelx.dobrowolski@intel.com>
