pmisch:

I wish to add a new device which "should" be supported but isn't in the list, yet.
It's a Deciso DEC740 with an AMD SoC v1500b. There is also the DEC750, DEC840 and DEC850 which are similar.

There were two commits regarding that SoC:
37958f0
1c4cd71

OpenWrt Nightly starts without errors. In dmesg I can see those lines:
[ 9.723673] kmodloader: loading kernel modules from /etc/modules.d/*

The problem is the links won't come up, no matter what I do . I tried to configure the interfaces in /etc/config/network or via "ip link set up eth3" but nothing happens, even no logs.
When I boot the Hardware with OPNsense (which is the stock firmware for those) the links come up fine.
