If DRAM calibration fails or mem test fails using the cached calibration
results stored in flash, rerun DRAM full calibration. If partial
calibration fails or the mem test following it fails, hang forever.
Partial calibration acts as a fallback approach in case of full
calibration failure. Therefore, if it fails, there would be no other
ways to initialize DRAM. Instead of falling into reboot loop and
draining out of battery, it is better to just hang so that the end user
may notice that and send to RMA.
