Subject: rockchip: px30: add uart5 as option for serial output
X-Git-Url: http://git.openwrt.org/%22https:/collectd.org//%22http:/www.crowdsec.net/%22/%22https:/collectd.org/%22http:/www.crowdsec.net/%22?a=commitdiff_plain;h=5f441a7b3db705cd1dd546f6e623586801da6c07;p=project%2Fbcm63xx%2Fatf.git

rockchip: px30: add uart5 as option for serial output

The px30 mini-evb can use either uart2 (muxed with the sd-card pins) or
uart5 via its pin header for serial output. Uart5 is especially useful
when needing to boot from the sd-card, where uart2 obviously is not
useable.

So add the uart5 constants and it as uart option for the serial-param
handler.
