Subject: Of the device tree binary format endianness on little-endian platform
Date: Wed, 18 Feb 2009 17:46:25 +0100	[thread overview]
Message-ID: <1234975585.17001.131.camel@pc-laurentg.intra.local> (raw)

Hi,

We are currently investigating the use of a flattened device-tree for
configuring some boot parameters on a new ARM platform. ARM being
little-endian, the first question that arise is whether we should keep
the .dtb binary format itself big-endian or switch to little-endian?
Apparently the format does not specify endianness specifically, and I
did not found any relevant information concerning this.

Perhaps this has already been decided somewhere on the roadmap of using
device-tree outside the PPC-world.

Any comments welcomed,

Laurent GREGOIRE
