[PATCH] hw: arm: aspeed: Enable eth0 interface for aspeed-ast2600-evb

[Guenter Roeck]

Commit 7582591ae7 ("aspeed: Support AST2600A1 silicon revision") switched
the silicon revision for AST2600 to revision A1. On revision A1, the first
Ethernet interface is operational. Enable it.

Indeed. 

I see that commit ba56f464f0c ("ARM: dts: aspeed: ast2600evb: Add MAC0")
reintroduced it a while ago. But my A0 doesn't support it. I am missing
something.

Joel, why this patch didn't reach the OpenBMC kernel ? 

Thanks,

Because your a0 doesn't support it, so it would break that. That's the
only reason.

It's queued to aspeed-6.2.
