We talked about this a lot about 15 months ago. It's a harder question
than it seems at first.
The problem is that we have to be careful to take the 'everything in
dts' only as far as it makes sense. Right now, we generate code from
the dts to C structs and do a lot of build-time checking.
As we add more things to dts, we should add more code generation. We
do not want to have a situation where we're doing this at runtime:
spdval = value("/dram/spd/tpr");
because there is lots of build time checking we lose (e.g. somebody
specifies a totally wacky 32-bit number for what is a u8 value).
I like the dts but I'm not sure we want every single thing in it. But
I'm not claiming that the balance is perfect .
