[OLPC-devel] Device tree

[Mitch Bradley]

[Changing name of thread...]

a) I think we need our own sub-architecture, sooner rather than later.  
I could give a bunch of reasons, but I suspect that they are obvious to 
everyone here, considering how little our hardware resembles a legacy PC.

b) Do we really need PCI autoconfiguration at this point?  The wiki 
hardware spec doesn't mention the mini-PCI connector.  Can we just 
pretend that it doesn't exist?  That would remove a lot of variables 
from the startup and suspend/resume sequence.  Removing unnecessary 
variables is a Very Good Thing.

c) I will go out on a limb and say that I could add rudimentary OF 
device tree support to either or both of LinuxBIOS and a custom kernel 
in a very short time.  Especially if the actual configuration is mostly 
known.  No methods, just properties.  You may well ask: Why bother with 
a device tree if the configuration is known?  The answer: Because when 
we do the 2nd generation hardware and kernel, we will wish that we had.
