You should have followed Rob's request here and made two patches for 
the binding document:

1. A 1-to-1 conversion of the text file to dt-schema
2. Add your new compatibles for the 2600.

>From a cursory glance it looks okay except for the new compatibles.

Regarding the compatibles, I'd prefer we use something a bit more 
meaningful. What do you think of these?

- aspeed,ast2600-sgpiom-80
- aspeed,ast2600-sgpiom-128

Cheers,

Andrew
