Re: Merging ppc32 and ppc64

quoted

I don't see the merge as changing the actual code that gets executed
on any given platform very much, except in one respect: we are going
to standardize on a flattened device tree as the way that information
about the platform gets passed from the boot loader to the kernel.
Comments? Flames? :)

There are several userspace applications that parse the non-flat 
device tree in /proc/device-tree on pSeries.  While I like the idea of 
the flattened device tree I think we need to consider how many apps we 
are going to break with it.

_Please_ don't throw the real device tree away; I'm happy with
the flattened device tree if and only if it is a _minimum_
requirement, and having a _real_ device tree (or even real
Open Firmware support) is still an option.
