Hi Florian,

thank you for first comments. It was my first Patchset i tried to send ia git 
send-email. i had searched the Patch 0/x-option but had not found it. i will 
rework this.

- i did only a porting to 4.15+ dsa-core. how do i credit John in this series?
- maybe i need a fallback to current "first cpu-port option", this was not 
defined by john, but i can add it in next series
- should i include dts (bananapi r2) also in the series?
- i have a additional patch renaming dts-option to default_cpu instead of cpu 
(hint of Andrew)

regards Frank
