4 Subject: [PATCH 01/29] arm: mediatek: retrieve ram_base from dts node for
5 armv8 platform
6
7 Now we use fdtdec_setup_mem_size_base() to get DRAM base from fdt ram node
8 and update gd->ram_base. CFG_SYS_SDRAM_BASE is unused and will be removed.
9
10 Also, since mt7622 always passes fdt to linux kernel, there's no need to
11 assign value to gd->bd->bi_boot_params.
