FW: [RFC PATCH 00/14] Versatile Express device tree port

[Dave Martin]

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

> It 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.
