From e2ed6c8e77fb810915a0f45d5f711d678469511f Mon Sep 17 00:00:00 2001 From: Martin Hicks Date: Mon, 21 Mar 2011 13:39:43 -0400 Subject: [PATCH] linux: Add support to specify special Kernel Image make target This is useful for ARCHes like PowerPC that have a whole lot of special targets for each different board. The kernel image target tells make which OpenFirmware machine description file is combined into the kernel binary.
