some switch-chips have multiple CPU-Ports
this patch-series adds basic functionality and handle the 2
cpu-Ports of mt7530 on board BananaPi R2
changes to mtk-ethernet-driver are not included yet,
because here are still some issues with watchdog-timeouts
most patches are based on OpenWRT-Patches created by
John Crispin and only ported to DSA-Core 4.15+ with 2 main differences:
- no change to platform-driver
- option in dts is named "default_cpu" instead of only "cpu" to
allow modification from userspace (additional patches needed)
complete source (including eth-patches) is uploaded here:
https://github.com/frank-w/BPI-R2-4.14/commits/4.20-gmac-test
new in v2:
- added DTS-changes
- added cover-letter
- added change of dts-option (default_cpu)
currently posted not to full maintainers-list for first review,
will do it when patches are ready :)
