Hi all,
Lorenzo has posted his Versatile Express fdt support work to the devicetree-discuss mailing list, copied below.
Be aware that this is still under discussion upstream, and very much a work in progress. There may be significant rebasing / fixes... so don't rely on it to be stable ;)
Cheers ---Dave

This patchset provides an initial version of device tree enabled kernel on an ARM Versatile Express board. The patchset applies to Jeremy Kerr's tree:
git://kernel.ubuntu.com/jk/dt/linux-2.6.git dtbimage commit: 4cb80ac96489220554d28f6fde527aeef83e628bThe patched kernel version is available on my public ARM git tree:
git://linux-arm.org/linux-2.6-lp.git ve-fdtIt has been tested on HW ARM Versatile Express board, with both static and DT configurations.
It contains fixes for generic device tree features and clock configuration, code to patch Versatile Express peripherals drivers and build system.
Clock names as well as amba device names are temporary waiting for OF bindings definition (clocks). The Versatile Express board specific init code has been split into DT and non-DT code in order to factor out common code between the two configs.
A static inline function has been added to the platform bus in order to initialize the OF match table and avoid cluttering code with preprocessor macros.
Drivers ( and GIC, sp804, PL310 specific code) device tree init is an initial stab at configuring peripherals with device tree data, so some choices especially concerning error codes are arguable and require thorough review.
The whole patchset is a request for comments on code and methodology.
Cheers.
