Summary
This change adds cache flushing for debug purposes. Normally, cache operations are unnecessary since the system reboots. However, flushing the cache is required when the system crashes, allowing us to retain the entire memory after rebooting into the bootloader, where a full memory dump and further analysis can be performed.
Impact
Should be minimal.
Testing
This feature was tested on an internal project. When the system crashes, it reboots into the bootloader and uses USB to transfer the full memory to the host for inspection.
