Hi Stefan (and anybody else that can answer),
I'm trying to understand why some 4xx boards use CONFIG_NET_MULTI and a few don't. Is there a technical reason why these few can't (limited storage or something else) or are they just older?
Yes, they are just older. Nobody found the time to clear this up till now.
There are 47 boards in-tree that use CONFIG_PPC4xx_EMAC and the following 18 use the older net API.
bwarren@bwarren-bldsrv:~/src/u-boot-net/include/configs$ grep -l PPC4xx_EMAC *
| xargs grep -L CONFIG_NET_MULTI
AR405.h CPCIISER4.h CRAYL1.h csb272.h csb472.h DP405.h ERIC.h EXBITGEN.h HUB405.h JSE.h MIP405.h OCRTC.h ORSG.h PIP405.h sbc405.h W7OLMC.h W7OLMG.h WUH405.h
I'd like to move all over to CONFIG_NET_MULTI,
That would be great. I thought about this as well but didn't find the time yet to do so.
which in itself is trivial since the EMAC driver supports both APIs, but am wary of breaking something.
The reason for this (as far as I overlook things) is simply historical. Nobody found the time to clear this up till now. Chances are good that such a transitions doesn't break anything. I can't test though, since I don't have access to any of those boards. I added Matthias to cc, he is maintaining some of those boards. Maybe he could test if you provided a patch for this?
Thanks.
Best regards, Stefan
