Qualcomm Technologies, Inc. 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 an alternate
EL1 application (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.
