this patch is only for dram-k.
mtk_dram_init internally calls dram_run_fast_calibration or dram_run_full_calibration so this is for dram calibration, but not only fast-k.

ddr_geometry and ddr_type are only used on 8192 and not used on 8195.
oh that's interesting. so you mean the 8195 dram init code will detect memory module and do everything without external info?
it can identify size, channels, banks, byte mode, ... etc everything?
