Re: [RFC] [PATCH] Device Tree on ARM platform
From: Mitch Bradley

If anybody is interested, the core ARM support has been added to the
Open Firmware tree at svn://openfirmware.info/openfirmware - the same
version of OFW that's used on OLPC - under an MIT-style license. This is
a full-featured Open Firmware whose lineage traces back to the original
Open Boot implementation that I wrote for Sun starting in 1987.
It's not yet fully elaborated for specific platforms and devices, but it
does contain all the core IEE1275 device tree stuff and the standard
support packages. It gets you to an ok prompt on Beagle Board and
Gumstix Overo systems. The source-level and assembly-language debuggers
are fully functional. As currently configured on those systems, you can
load it into memory either via u-boot or instead of u-boot.
This base ARM port, while newly released as FOSS, is quite solid, having
been developed some years ago for the Digital (RIP) DNARD system.
I'd be happy to work with people to add deeper support for specific
device and platforms.
