Subject: ram: rk3399: Simplify data training first argument
X-Git-Tag: v2019.10-rc1~20^2~73
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=e6ae37a007c2ddc5f070c8ce65349b472e625060;p=oweals%2Fu-boot.git

ram: rk3399: Simplify data training first argument

data training is using chan_info as first argument with
channel number as second argument instead of that use
dram_info as first argument so-that we can get the
chan_info at data training definition.

This was the argument handling is meaningful, readable
and it would help to add similar data training for
lpddr4 in future.
