From a4da2e3ec84cda635ac441efbe781a38d2ee41ee Mon Sep 17 00:00:00 2001 From: David Gibson Date: Tue, 18 Dec 2007 15:06:42 +1100 Subject: [POWERPC] Merge dtc upstream source This incorporates a copy of dtc into the kernel source, in arch/powerpc/boot/dtc-src. This commit only imports the upstream sources verbatim, a later commit will actually link it into the kernel Makefiles and use the embedded code during the kernel build.
