From 63336ec7fd7d480ac58a91f3b20d08bf1b3a13ad Mon Sep 17 00:00:00 2001
From: Weijie Gao <weijie.gao@mediatek.com>
Date: Wed, 19 Jul 2023 17:15:41 +0800
Subject: [PATCH 01/29] arm: mediatek: retrieve ram_base from dts node for
armv8 platform
Now we use fdtdec_setup_mem_size_base() to get DRAM base from fdt ram node
and update gd->ram_base. CFG_SYS_SDRAM_BASE is unused and will be removed.
Also, since mt7622 always passes fdt to linux kernel, there's no need to
assign value to gd->bd->bi_boot_params.
