SoC vendors have different types of resets and are controlled through
various registers. For instance, Qualcomm chipsets can reboot to a
"download mode" that allows a RAM dump to be collected. Another example
is they also support writing a cookie that can be read by bootloader
during next boot. PSCI offers a mechanism, SYSTEM_RESET2, for these
vendor reset types to be implemented without requiring drivers for every
register/cookie.
Add support in PSCI to statically map reboot mode commands from
userspace to a vendor reset and cookie value using the device tree.
A separate initcall is needed to parse the devicetree, instead of using
psci_dt_init because mm isn't sufficiently set up to allocate memory.
Reboot mode framework is close but doesn't quite fit with the
design and requirements for PSCI SYSTEM_RESET2. Some of these issues can
be solved but doesn't seem reasonable in sum:
1. reboot mode registers against the reboot_notifier_list, which is too
early to call SYSTEM_RESET2. PSCI would need to remember the reset
type from the reboot-mode framework callback and use it
psci_sys_reset.
2. reboot mode assumes only one cookie/parameter is described in the
device tree. SYSTEM_RESET2 uses 2: one for the type and one for
cookie.
3. psci cpuidle driver already registers a driver against the
arm,psci-1.0 compatible. Refactoring would be needed to have both a
cpuidle and reboot-mode driver.

QCS9100 & QCS9075 are its IOT variants (with marketing name as IQ9) which inherit the memory map of SA8775P require a slightly different memory map as compared to SA8775P auto parts. This new memory map is applicable for all the IoT boards which inherit the initial SA8775P memory map. This is not applicable for non-IoT boards. Some new carveouts (viz. gunyah_md and a few pil dtb carveouts) have been introduced as part of firmware updates for IoT. The size and base address have been updated for video PIL carveout compared to SA8775P since it is being brought up for the first time on IoT boards. The base addresses of the rest of the PIL carveouts have been updated to accommodate the change in size of video since PIL regions are relocatable and their functionality is not impacted due to this change. The size of camera pil has also been increased without breaking any feature. The size of trusted apps carveout has also been reduced since it is sufficient to meet IoT requirements. Also, audio_mdf_mem & tz_ffi_mem carveout and its corresponding scm reference has been removed as these are not required for IoT parts. Incorporate these changes in the updated memory map.

commit 2a6c727 ("cpufreq: Initialize cpufreq-based frequency-invariance later") postponed the frequency invariance initialization to avoid disabling it in the error case. This isn't locking safe, instead move the initialization up before the subsys interface is registered (which will rebuild the sched_domains) and add the corresponding disable on the error path.
