Re: [PATCH] arm64: zynqmp: Do not clear reset reason

út 9. 2. 2021 v 8:52 odesílatel Michal Simek michal.simek@xilinx.com napsal:

There is no need to clear reset reason register because it is protected by PMUFW already which is reported when verbose log is enabled as: pm_core.c@733 APU> No write permission to 0xFF5E0220
