ipq40xx: Remove unused reserved-memory nodes The reserved-memory regions are mostly undocumented by QCA and are named very unspecific in the QSDK device trees. It was tried to clean them up by commit 71ed9f10a33e ("ipq40xx: Use detailed reserved memory for A42") and similar changes. The features which require these regions were mostly unknown but Senthilkumar N L <snlakshm@qti.qualcomm.com> and Sricharan Ramabadhran <srichara@qti.qualcomm.com> provided some more insight in some of them: * crash dump feature - a couple of regions used when 'qca,scm_restart_reason' dt node has the value 'dload_status' not set to 1 + apps_bl <0x87000000 0x400000> + sbl <0x87400000 0x100000> + cnss_debug <0x87400000 0x100000> + cpu_context_dump <0x87b00000 0x080000> - required driver not available in Linux - safe to remove * QSEE app execution - region tz_apps <0x87b80000 0x280000> - required driver not available in Linux - safe to remove * communication with TZ/QSEE - region smem <0x87b80000 0x280000> - driver changes not yet upstreamed - must not be removed because any access can crash kernel/program * trustzone (QSEE) private memory - region tz <0x87e80000 0x180000> - must not be removed because any access can crash kernel/program Removing the unnecessary regions saves some kilobyte of reserved-memory and cleans up the device tree: * 2560 KiB - 8devices Jalapeno - AVM FRITZ!Box 4040 - Compex WPJ428 - Meraki MR33 Access Point - OpenMesh A42 * 14336 KiB - GL.iNet GL-B1300 - Qualcomm Technologies, Inc.
