(TARGET_​TEMPERATURE)

Target DDR temperature in units of DRAM MR4. SoC will apply throttling action in case this temperature exceeded.
The default target value is 01001B (0x9) which corresponds to DRAM maximum operating temperature of 85°C as specified by JEDEC DDR specification.
Intel recommends to use the above target temperature as the POR, any other target temperature is the sole responsibility of the customer.
