Aspeed don't make this, do they?

Take a look at the other examples (or your device tree in the kernel,
which you should base this one on):

        model = "Facebook Bletchley BMC";
        compatible = "facebook,bletchley-bmc", "aspeed,ast2600"

I suggest ignoring the company rename to keep things simple, but I'll
leave that to you.

The rest looks good. Thanks!
