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 > -----Original Message----- > From: Lorenzo Pieralisi > Sent: 18 August 2010 20:00 > To: devicetree-disc...@lists.ozlabs.org; grant.lik...@secretlab.ca > Cc: li...@arm.linux.org.uk; n...@fluxnic.net; Catalin > Marinas; Philippe Robin; jeremy.k...@canonical.com > Subject: [RFC PATCH 00/14] Versatile Express device tree port > > This patchset provides an initial version of device tree > enabled kernel on an ARM Versatile Express board.
