2022-03-23src/mediatek/mt8186: Implement sdram_size() to get real dram sizeXi Chen
Originally, dram size is hard-coded to 4GB by default. To support different dram size, calculate it from the mem chip info stored in CBMEM. BUG=b:206014043 TEST=Output "dram size: 0x100000000" on Kingler Signed-off-by: Xi Chen <xixi.chen@mediatek.corp-partner.google.com> Change-Id: I017e9d1a2d6e26f1fc21b67b5962dfb5c6ade8a5 Reviewed-on: https://review.coreboot.org/c/coreboot/+/62065 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Yu-Ping Wu <yupingso@google.com>
