Subject: rockchip: fix set default serial_{addr,port} in boot script
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=609deedd87ed66718653a799a68fa3b52da844f7;p=thirdparty%2Fopenwrt.git

rockchip: fix set default serial_{addr,port} in boot script

On some SoCs like RK3399, U-Boot no longer export the serial
address in $stdout variable, it has been changed to something like
`stdout=serial,vidconsole` since video supported was added. So
detect $soc variable instead, this also makes the script more clear.

Addtional note: rk3566 is reported as rk3568, rk3582 is reported as
rk3588 in $soc.
