From e2ad477cb26360532da7ee9ffc9631d6c0006a1d Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Sun, 25 Sep 2016 22:35:41 +1000 Subject: [PATCH] powerpc: Set default CPU type to POWER8 for little endian builds We supported POWER7 CPUs for bootstrapping little endian, but the target was always POWER8. Now that POWER7 specific issues are impacting performance, change the default target to POWER8.
