From c74675bd904b6ce9d5820a80f27793c0583fd54c Mon Sep 17 00:00:00 2001 From: Nandor Han Date: Thu, 10 Jun 2021 16:56:45 +0300 Subject: reboot-mode: read the boot mode from RTC memory RTC devices could provide battery-backed memory that can be used for storing the reboot mode magic value. Add a new reboot-mode back-end that uses RTC to store the reboot-mode magic value. The driver also supports both endianness modes.
