Replace 'support_33bits with 'dma_max_support' for DMA mask operation, and replace 'mtk_i2c_set_4g_mode' with 'upper_32_bits'.This doesn't explain why we need this patch. How about: Newer MTK chip support more than 8GB of dram. Replace support_33bits with more general dma_max_support.
ok, Thanks for your comments.
