From 6d1970fa8a8d315af2b5c2c6f0ad5e5c24a382b5 Mon Sep 17 00:00:00 2001 From: Kever Yang Date: Fri, 23 Jun 2017 16:11:05 +0800 Subject: rockchip: add sdram_common for common functions There are some functions like sdram_size_mb can be re-used for different rockchip SoCs, just put them into common file. Add board_get_usable_ram_top() for ram_top init base on SDRAM_MAX_SIZE.
