SoCs do not guarantee that an architectural warm reset boots back into Linux kernel. For instance, if download mode or reboot reason cookies are set, the SoC would do a warm reset into an alternate exception level (e.g. a mode to collect RAM dumps) or application at EL1 (e.g. fastboot mode). Thus, Qualcomm Technologies, Inc. SoCs support a vendor-specific warm reset type that can be used in all instances of warm/soft reboots.
