From: Kever Yang Date: Fri, 15 Nov 2019 03:04:33 +0000 (+0800) Subject: ram: rockchip: rename sdram_common.c/h to sdram.c X-Git-Tag: v2020.01-rc3~2^2~63 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=5d19ddf0dbee50f6bf92536c45ebd66173683c51;p=oweals%2Fu-boot.git ram: rockchip: rename sdram_common.c/h to sdram.c rename sdram_common.c in arch/arm/mach-rockchip to sdram.c; so that we can use the file name sdram_common.c in dram driver for better understand the code; clean the related file who has use the header file at the same time.
