X-Git-Tag: v2019.10-rc1~20^2~20
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=19d0de3ee4d0f4fc13f09303fbbe91bf8d8d81d8;p=platform%2Fkernel%2Fu-boot.git

rockchip: rk3036: sdram: use udelay instead of rockchip_udelay

Use system api for udelay instead of vendor defined api,
and rockchip_udelay() will be removed.
