Subject: rockchip: rk322x: move board_debug_uart_init() to rk322x.c
X-Git-Tag: v2019.07-rc2~29^2~7
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=28fe4d5b304d52940b6928bb0ff9009b5c012d92;p=platform%2Fkernel%2Fu-boot.git

rockchip: rk322x: move board_debug_uart_init() to rk322x.c

Move the function to soc file so
that we can find all the soc/board setting in soc file and
use a common board file later for all rockchip SoCs.
