Hi julius:
  MTK structure mr8_sensity array stores each rank's density.
  For each channel density, they are always equal.
  Take rank_nums = 2 as example:
  total_size == mtk_dram_size() 
             == ddr->mrr_info.mr8_density[0] + ddr->mrr_info.mr8_density[1]
  CH0/RK0 size: ddr->mrr_info.mr8_density[0] / 2
  CH0/RK1 size: ddr->mrr_info.mr8_density[1] / 2
  CH1/RK0 size: ddr->mrr_info.mr8_density[0] / 2
  CH1/RK1 size: ddr->mrr_info.mr8_density[1] / 2

Thanks.
