From 973193554cae6b055474964f995e36c42d195137 Mon Sep 17 00:00:00 2001 From: Shahar S Matityahu Date: Mon, 8 Apr 2019 10:57:09 +0300 Subject: iwlwifi: dbg_ini: dump headers cleanup Unite dump memory ranges under a single struct and add a specific header for each type of memory. Also, maintain a single version to all dump structures. This cleanup is also needed for the future addition of FW notification regions and others.
