From d72b08017161ab385d4ae080ea415c9eb7ceef83 Mon Sep 17 00:00:00 2001 From: Ian Munsie Date: Mon, 23 Sep 2013 12:05:11 +1000 Subject: powerpc: Add ability to build little endian kernels This patch allows the kbuild system to successfully compile a kernel for the little endian PowerPC64 architecture. A subsequent patch will add the CONFIG_CPU_LITTLE_ENDIAN kernel config option which must be set to build such a kernel. If cross compiling, CROSS_COMPILE must point to a suitable toolchain (compiled for the powerpc64le-linux and powerpcle-linux targets).
