2019-10-18soc/mediatek/mt8183: Pass impedance data as a function argumentYu-Ping Wu
To make data flow more explicit, global variable 'impedance' is replaced with a local variable, which is passed as a function argument.

2019-10-17soc/mediatek/mt8183: Handle memory test failureYu-Ping Wu
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.

2019-10-09soc/mediatek/mt8183: Use cached calibration result for faster bootupHuayang Duan
Load calibration params from flash. If the format of the params is correct, use these calibration params for fast calibration to reduce the bootup time. Bootup time of DRAM partial calibration: - 1,349,385 usecs with low frequency - 924,698 usecs with middle frequency - 1,270,089 usecs with high frequency 3,544,172 usecs in total. Bootup time of DRAM fast calibration: - 216,663 usecs with low frequency - 328,220 usecs with middle frequency - 322,612 usecs with high frequency 867,495 usecs in total.
