From 999159a5381bff3bd6f688c5d20fbec9d8789e53 Mon Sep 17 00:00:00 2001 From: Vineet Gupta Date: Tue, 22 Jan 2013 17:00:52 +0530 Subject: ARC: [DeviceTree] Basic support This is minimal infrastructure needed for devicetree work. It uses an a sample "skeleton" devicetree - embedded in kernel image - to print the board, manufacturer by parsing the top-level "compatible" string. As of now we don't need any additional "board" specific "machine_desc".
